    for now i have a button bypassing the lock, it works find just at the end of cycle its not unlocking therefore i get an error again (which is annoying but livable ) i am thinking of adding an arduino micro-controller to take over the locking unlocking part ( 3$ vs ~200$ )
    but the best solution will be as i asked to replace the correct component on the board.

Key fob not working on front passenger side but works all other doors. I changed the actuator. 2012 ford fusion. Any Ideas will help

Does your fusion have Power Door Locks - Without Memory or Power Door Locks - With Memory ? Do you know about ford SJB - smart junction box ?

Power Door Locks - Without Memory
Regardless of the key position, the smart junction box (SJB) is supplied voltage at all times. When the SJB receives a signal from the remote keyless entry (RKE) transmitter, the keyless entry keypad, or the door lock control switches, the SJB supplies a ground signal to the appropriate lock or unlock relay. The ground signal closes the relay which supplies voltage to the door lock actuators. The door lock actuators then actuate to a lock or unlock position.
Power Door Locks - With Memory
Regardless of the key position, the SJB and the driver door module (DDM) are supplied voltage at all times. When the SJB receives a signal from the RKE transmitter, the keyless entry keypad, or either door lock control switch, the SJB sends a command to the DDM, through the controller area network (CAN), and a ground signal to the lock and unlock relays. When the LH door lock control switch is pressed, the DDM receives the lock or unlock signal. The DDM will send a request through the CAN network to the SJB to lock or unlock the passenger doors. The SJB then responds to the DDM request, authorizing a lock or unlock of the driver door by the DDM. The DDM then supplies voltage and ground to the driver door lock actuator based on the lock or unlock request. The ground signal in the SJB closes the relay which supplies voltage to the remaining door lock actuators. The remaining door lock actuators then actuate to a lock or unlock position determined by the relay.

2012 Equinox. Door locks operate intermittently (once every few days), so it isn't a wire or a fuse. My bet is that it is a relay or the body control module.

Did you hook up a professional grade scan tool an check BCM codes ,view live input data for power locks .
Door Lock System Components
The power door lock system consists of the following components:
• Driver door lock switch--Provides a switched voltage signal to the body control module (BCM) for both lock and unlock switch activations.
• Front passenger door lock switch--Provides a switched voltage signal to the BCM for both lock and unlock switch activations.
• Door lock relay--Located in the instrument panel (I/P) fuse block and controls the locking of all doors and liftgate.
• Door unlock relay--Located in the I/P fuse block and controls the unlocking of the passenger doors and liftgate.
• Driver door unlock relay--Located in the I/P fuse block and controls the unlocking of the driver door.
• BCM--Class 2 module which requires programming when replaced
• Reversible door lock actuators in each of the doors
• LOCK/MIRROR 10 A fuse--Located in the I/P fuse block, supplies power for the door lock switches and relays.
• DR LCK 20 A fuse--Located in the I/P fuse block, supplies power to the relays.


DTC Descriptors

The relays in the I/P fuse box are not listed because you can't change them so why show then . They are PCB - relays Printed circuit board relays , soldered directly to the circuit board inside the fuse box.

You best bet ,take it to a qualified repair shop. I would say the vehicle has a lose connection somewhere . Ground ,


My bet is that it is a relay or the body control module. ??? Then you would be wrong Take it to a professional before you start replacing parts it doesn't need .

How can I open my trunk on a 98 Buick Century that has no trunk release button in the car and no key to the trunk without busting the lock or taken out the back seat

Do you have keyless entry ?
The remote keyless entry system performs the following functions:
• Locking the vehicle doors
• Unlocking the vehicle doors
• Opening the rear compartment lid

Rear Compartment Lid Release Circuit Description
The BCM receives a signal via Class II from the PCM indicating the position of the transaxle range switch. When you press the release button on the RKE transmitter, a signal is sent from the remote control door lock receiver through circuit 377 to the BCM. Then, the BCM sends a ground signal through circuit 253 to the rear compartment lid release relay. The relay receives power from the DOOR LOCKS fuse. When the relay receives the ground from the BCM, the relay's internal switch closes sending B+ (via circuit 56) to the rear compartment lid lock release actuator. A ground is always supplied to the actuator through circuit 350. When B+ is received at the actuator through circuit 56, the rear compartment lid releases.

You could jumper pins at the rear compartment lid release relay , this would open it .

Power Door Locks Circuit Description
Models Without Keyless Entry
When either door lock switch is pressed in the power door locks system, all doors lock or unlock in unison. Each lock can also be operated manually from the locking knob.
The locks are operated by reversible actuators that receive voltage from the door lock relay assembly's two built-in relays. The relays energize the actuators by applying voltage to one of the terminals and ground to the other terminal. In order to reverse the actuators, the polarity to the terminals is reversed.
The door lock switches are usually closed briefly. If the door lock switches are held closed, a circuit breaker in each actuator will open to protect against damage. The circuit breaker resets only after voltage is removed from the actuator.
Lock Operation
Pressing the lock position on either door lock switch sends a voltage signal in CKT 195.
Pressing the lock position turns on the lock relay located inside the door lock relay assembly. The lock relay completes the circuit that supplies voltage to CKT 295. CKT 295 is the voltage feed to the actuators.
At this time, the unlock relay is not energized. When the unlock relay is off, CKT 294 is grounded, which provides a ground path to the door lock actuators.
The entire action described completes the electrical circuit the actuators in each door, thus locking the doors.
When the door lock switch is released, the lock relay contact closes to ground, and the actuators turn off.
Unlock Operation
Pressing the unlock position on either door lock switch sends a voltage signal in CKT 194.
Pressing the unlock position turns on the unlock relay located inside the door lock relay assembly. The unlock relay completes the circuit that supplies voltage to CKT 294. CKT 294 is the voltage feed to the actuators.
At this time, the lock relay is not energized. When the lock relay is off, CKT 295 is grounded, which provides a ground path to the door lock actuator.
The entire action described completes the electrical circuit to the actuators in each door, thus unlocking the doors. The polarity of the voltage to the actuators has reversed, causing the actuators to run in the opposite direction in order to unlock the doors.
Models Equipped With Keyless Entry
All door locks operate the same as vehicle models equipped without keyless entry, except the left front door lock.
Lock Operation
Pressing the lock position on either door lock switch sends a voltage signal in CKT 195.
Pressing the lock position turns on the lock relay located inside the door lock relay assembly. The lock relay completes the circuit that supplies voltage to CKT 295. CKT 295 is the voltage feed to the actuators.
At this time, the lock relay is not energized. When the lock relay is off, CKT 295 is grounded, which provides a ground path to all door lock actuators, except left front door lock actuator.
The left front door actuator is grounded through the Remote Control Door Lock Receiver, RCDLR, CKT 694. The RCDLR has a built-in relay. When the built-in relay is de-energized, the relay provides a path to ground to the left front door actuator.
The entire action described completes the electrical circuit to the actuators in each door, thus locking the doors.
When the door lock switch is released, the lock relay contact closes to ground, and the actuators turn off.
Unlock Operation
Pressing the unlock position on either door lock switch sends a voltage signal in CKT 194. The signal is sent to both the unlock relay located inside the door lock relay and the Remote Control Door Lock Receiver, RCDLR.
Pressing the unlock position turns on the unlock relay, and signals the RCDLR to unlock the left front door. the unlock relay completes the circuit that supplies voltage to CKT 294. CKT 294 is the voltage feed to the actuators, except the left front door lock actuator.
The left front door actuator receives voltage through the Remote Control Door Lock Receiver, RCDLR, CKT 694. the RCDLR has a built-in relay. When the built-in relay is energized, the relay provides a voltage to the left front door actuator. The RCDLR energizes the relay when it receives a voltage in CKT 194.
At this time, the lock relay is not energized. When the lock relay is off, CKT 295 is grounded, which provides a ground path to all door lock actuators.
The left front door actuator is grounded through the Remote Control Door Lock Receiver, RCDLR, CKT 694. The RCDLR has a built-in relay. When the built-in relay is de-energized, the relay provides a path to ground the left front door actuator.
The entire action described completes the electrical circuit to the actuators in each door, thus locking the doors.
When the door lock switch is released, the unlock relay contact closes to ground, the RCDLR left door unlock control relay contacts close to ground, and the actuators turn off.

2012 ford f350 door locks only work manually key fob has been dead for years now door lock button does not work cant seem to find fuse location in my book ?

None of the door power lock's work ? Not from any switch ? F32 - 15 amp fuse location - body control module (BCM) . Probably not a fuse issue , door locks are controlled by the BCM controlling relay's located inside the BCM . This relay's are PCB - printed circuit board relay's , non serviceable . Your best bet , take it to a qualified repair shop .

Power Locks
The Body Control Module (BCM) monitors the door lock control switches. When the BCM receives an unlock/lock command from either door lock control switch, the BCM energizes a relay (internal to the BCM ) to supply the correct power and grounds for the door lock actuators.

Remote Keyless Entry (RKE)
The Remote Keyless Entry (RKE) feature is controlled by BCM . The BCM receives the RKE inputs from the Tire Pressure Monitor (TPM) module over the Medium Speed Controller Area Network (MS-CAN) . When any RKE transmitter button is pressed, the signal is received by the TPM module internal antenna. The TPM module then filters the RKE signal received to make sure it is a programmed transmitter. If the signal received is from a programmed transmitter, the TPM module sends the RKE command to the BCMover the MS-CAN . The BCM then interprets the RKE command and activates the corresponding output.
The BCM requests the illuminated entry feature to turn the interior lamps on when an unlock command is received. If a lock command is received, the illuminated entry feature turns off. The BCM then supplies voltage to the appropriate door lock actuator(s) to lock or unlock the doors. The RKE transmitter can also be used to activate the panic alarm. On vehicles with memory, the RKE transmitter also causes the BCM to send a MS-CAN message to the Driver Seat Module (DSM) to activate all memory features to the positions associated with the RKE transmitter being used.

2008 Chevy Impala LTZ: car wont lock or unlock with the power lock/unlock buttons on the remote or car door. It makes a clicking sound though when I attempt to. Is this a blown fuse? Or something else

Where do you here the clicking sound ? in the door , behind instrument panel ? I don't think a blown fuse would do this , possibly a relay ! do you know what a relay is ? This is Chevy factory service information !
Door Lock Operation
When the body control module (BCM) detects a transition of either of the door lock switches to the lock position, it switches the door lock actuator lock control circuit to voltage. Since the lock actuator unlock control circuits are at ground potential within the BCM, the door lock actuator motors transition to the lock position.
There are three pcb relays integrated into the instrument panel fuse box ( non replaceable ) door unlock pcb relay drivers door -door unlock pcb relay an door lock pcb relay ! The BCM controls these relays ! Do you know what a BCM is ?
Circuit/System Description
The DR/LCK fuse supplies battery positive voltage to the I/P fuse block for the door lock system. The body control module (BCM) supplies and monitors a reference voltage to the door lock switch through the door lock switch lock/unlock signal circuit. The door lock switch also receives a constant ground source. If a door lock switch is placed in the lock position or unlock position, the reference voltage is taken directly to ground and the BCM detects the voltage drop on the signal circuit.
The BCM, upon receipt of a door lock switch lock or unlock signal, will switch the appropriate door lock actuator control circuits to battery positive voltage. The opposing side of the door lock actuators are connected to ground internally within the BCM through the other door lock actuator control circuit and the doors will lock or unlock appropriately.
With out have a factory GM tech 2 scan tool ,It would be best if you took this to a Chevy dealer . The first part of diagnosing this problem is to hook up a scan tool !

Principles of Operation
Power Door Locks
The generic electronic module (GEM) controls the power door lock and keyless entry system. Lock and unlock operation is achieved through the use of internal relays in the GEM. The relays are all door lock, all door unlock and driver door unlock. The normal path of the relays is to ground.
Pressing the door lock control switch to lock or unlock sends a ground signal to the GEM. The same GEM pin is used for unlock and lock input. The unlock signal is a direct connection to ground. The lock signal is altered by an internal resistor in the door lock control switch. This varied resistance identifies lock or unlock command to the GEM.
The door locks can also be controlled by the door key cylinder switches. For the liftgate door lock switch, turning the key to lock or unlock sends a ground signal to the GEM. The GEM will then ground the all door lock or all door unlock relay supplying voltage to the actuators. Turning the driver door key cylinder to the lock position sends a ground signal to the GEM. The GEM will then ground the all door lock relay supplying voltage to the actuators. Turning the driver door key cylinder to unlock sends a ground signal to GEM. The GEM will ground the driver door unlock relay and supply voltage to only the driver door actuator. If a second unlock ground is received within three seconds of the first, the GEM will ground the all door unlock relay supplying voltage to the passenger door actuators (if 2-stage unlock is equipped).
Keyless Entry
The keyless entry remote transmitter sends a signal that is received by the GEM internal antenna. Depending on the signal received, the GEM module will ground the appropriate internal relay and lock all doors or unlock the driver door. If the unlock signal is received again within three seconds of the first unlock, the GEM will ground the internal all door unlock relay unlocking all doors. The lock and unlock relay output to the actuators is controlled by the GEM, the same as power door lock operation from the control switch.
If the signal received is for the panic button, the GEM will cycle ground to the park lamp relay coil and horn relay coil. The park lamps and horn will continue to cycle until the panic button is pressed again or the ignition switch is turned to the RUN position, or after the timer expires.

2002 door locks failed ford escape

Using a multimeter, check for voltage at the lock/unlock solenoid. Disconnect the connector and probe the unlock side with the other lead on a good ground. Hit the unlock twice and see if you get voltage. If yes, the solenoid may be defective or if not, you could possibly have a bad relay. Even though you can hear the relay, that doesn't necessarily mean it's completing the circuit. My car did the same thing and I ended up replacing the relay.
The lock side check would be the same.

Hope this helps!
