Question about 2006 Pontiac Torrent

1 Answer

My hatch won't release from the remote or the door switch. No solenoid sound at the hatch. How do I get it to open if it's not a bad fuse?

It looks like it has one relay to unlock the drivers door and one relay to unlock the other three doors and the hatch. I only see one electric lock fuse in the owner manual. Where do I access the mechanism so I can release the latch to open the hatch, inside the car or from the outside at the tag light area?

There are actually three relays , an there are controlled by the BCM - body control module !
When a door lock switch is activated in the lock or unlock position the BCM will receive a voltage signal on either the door lock switch lock or unlock signal circuits.
The BCM, upon receipt of a lock switch lock or unlock signal, will switch the appropriate lock relay control circuits to battery positive voltage. This will energize the appropriate lock or unlock relays. The relay will supply voltage to the door lock actuator lock or unlock control circuits to one side of the lock actuator. Since the opposing side of the lock actuators are connected to ground through the other lock actuator control circuit and the normally closed contacts of the lock or unlock relay, the doors and liftgate will then lock or unlock appropriately.
Three relays are used to operate the locks. DRV DR UNLCK relay, PASS DR UNLOCK and DR LCK relay. This is done to isolate the driver door lock actuator so it can be unlocked by itself using the keyless entry transmitter.
Rear Hatch/Gate Description and Operation
The liftgate can be opened by operating the switch on the instrument panel. Battery voltage is supplied to the liftgate actuator through the body control module (BCM). The BCM will pulse the liftgate actuator when a release input is received through the key fob, or the instrument panel switch.
Door/Lift gate Latch Assembly

  1. Install a 20-A fused jumper wire between the control terminal 3 and 12 volts. Install a jumper wire between the ground terminal 2 and ground.
  2. Verify the actuator turns on & off.

If the function does not perform as specified, replace the applicable door latch.

What fuse is it for rear hatch actuator 99envoy


One fuse powers all door lock actuators . The other door locks work ? if so it's not a fues problem .
The following locking functions are included on the vehicle:
• All the doors unlock -- All the doors will unlock, including the endgate/liftgate, when any power door unlock switch is detected. The passenger doors lock directly by pressing the lock switches. The driver door unlocks by the BCM using a driver door unlock relay.
• All the doors lock -- All the doors will lock, including the endgate/liftgate, when any power door lock switch is activated. All the lock actuators will activate directly from the power door lock switch (external to the BCM).
• The end/lift gate lock switch -- All the doors will lock or unlock from the end/lift gate lock switch

You probably have a bad lock actuator

I have a 2005 GMC Yukon that the rear hatch does not lock. Wouldn't be a problem but no manual key hole to lock it. Must be some kind of lock sensor. Is on the driver door panel or by the hatch?


The rear hatch locking is computer contolled .
The BCM also runs diagnostics on the liftgate lock relay control circuit and will set DTC B3825 as current and also send a Class 2 message to the DIC. The DIC will display REPLACE LIFTGATE FUSE to inform the driver that a fault has been detected in the liftgate lock circuit and that the liftgate is not locked. Faults that will set the DTC and cause the DIC to display the message could be any of the following:
• An open ECC fuse
• An open or short to ground in the liftgate lock relay battery positive voltage circuit
• A faulty liftgate lock relay
• An open or short to ground in the liftgate lock relay control circuit
• A short to ground in the liftgate lock actuator lock control circuit
• A faulty BCM

The liftgate lock relay supply and coil sides receive a constant voltage through the battery voltage supply circuit and the ECC fuse. The normally closed contact is connected to ground and the control side is connected to the body control module (BCM). A lock function will occur when a door lock switch activation, keyless entry lock transmission, auto door lock function or a liftgate lock function has been received by the BCM. The BCM will then ground the control side of the liftgate lock relay. This energizes the relay and allows voltage to be applied to the liftgate lock actuator lock control circuit. Since the other side of the liftgate lock actuator is connected to the normally closed contacts of the door unlock relay to ground, the liftgate will lock. When an unlock function occurs the BCM will ground the control side of the unlock relay and the rear doors and liftgate will unlock.
The power door lock system consists of the following components:
• The driver door module (DDM)
• The passenger door module (PDM)
• The body control module (BCM)
• The driver information center (DIC)
• The rear door lock switch
• The door lock relay
• The door unlock relay
• The liftgate lock relay--utility vehicles with liftgate only
• The reversible door lock actuators in each of the doors and liftgate
• LOCKS 20A fuse (rear lock/unlock relay supply voltage)
• ECC 10A fuse (liftgate lock relay supply voltage)

If i were to guess i would say you mite need a new lock actuator , but i don't guess . You could take the hatch inside panel off an check for B+ voltage for the lock actuation as someone pushes the switch . Or have it checked for codes .

Power locks wont lock doors with switch


All doors? Check the fuse...see owner's manual for info. Also verify that it is the vehicle's lock switches...or the keyless entry fob. If it is a single door, this can be a tricky difficult ordeal to find the "source" of the problem.
The difficulty is due to the fact that the negative/positive wires reverse polarity at door lock relays each time the lock is electrically exercised. The locks are activated by an electromagnet solenoid, which reverse when the supply current reverses polarity. For example, you may be able to lock a door with the switch then not be able to unlock it...or vice versa. If one of the wires has a fault, and the door locked [or unlocked], the relay was also "tripped/switched" with the "good" wire. When that happened, the relay effectively reversed the wire polarities...meaning that the faulty wire cannot energize the relay/solenoid to activate the lock-unlocking mechanism to reverse the process..

Simply, put...this is not likely a do-it-yourself fix, unless you have fair DC electrical skills, and a shop manual with complete wiring diagrams. The problem could be a poor wire connection, a broken wire, a faulty relay, a faulty solenoid, or a combination of these...or even a physical fault in the mechanical linkage for the lock.

If your vehicle has a locking lifting hatch back...and this is the "door" that won't operate, this can be very aggravating as there is no manual override, without removing the door/hatch trim and manually moving the linkage.

Hopefully it is the fuse.....good luck.

Power Door Locks Circuit Description
The power door lock system incorporates door lock switches on both front doors and on the RH D-pillar, door lock motors in all passenger doors and in the RR cargo door, a door lock relay and a door lock control module.
Power for the door lock switches and the door lock control module is supplied from the CIG LTR fuse 13 through CKT 640 (ORN). Power for the door lock relay is supplied from the PWR ACCY circuit breaker through CKT 540 (ORN). Ground for the door lock relay is supplied from G202 through CKT 150 (BLK) and ground for the door lock control module is supplied from G400 through CKT 150 (BLK).
The door lock motors are reversible and both sides are connected to the normally closed contacts of the door lock relay. Those contacts of the relay are connected to G202. When any of the door lock switches are placed in the lock position, voltage is supplied through CKT 195 (LT BLU) to the relay lock coil. Since the other side of the lock coil is connected to ground, the coil is energized and it pulls the lock contacts closed. Voltage is then supplied through CKT 295 (GRY) to all the door lock motors and the doors lock. The unlock function operates in much the same manner except that when any of the switches are placed in the unlock position, voltage is supplied through CKT 194 (WHT) to the unlock coil of the relay and CKT 294 (TAN) supplies voltage to the apposite side of the door lock motor and the doors unlock.
Door Lock Control Module Description
The door lock control module is used on vehicles equipped with cargo doors. The purpose of the module is to lock the cargo doors after a lock cycle has been commanded from any of the door lock switches with the cargo doors open. When the RH cargo door is open, the module receives a ground signal from the closed contacts of the rear door jamb switch on CKT 1897 (ORN/BLK) to G400. When a lock command is received, the module retains this input until it receives an open input from the rear door jamb switch. Then the module sends a lock command through CKT 194 (WHT) to the door lock relay and the doors lock.
Rear Cargo Doors Description
The power door lock motor will not operate unless the rear cargo doors are fully closed. The power door lock motor is in the right cargo door. The contactors are on the rear cargo door opening on the body and on the right cargo door.

In the i/p fuse box there is 2 relays, a lock relay and an unlock relay. The relays should be the same. If the door lock actuators work in the lock position but not the unlock position try swapping the relays and see if the actuators will unlock the doors. You have a bad relay if this worked for you.

The only other part that is common to the circuits is the body control module. It controls the ground circuits to the lock relays. The control to the unlock side can be bad if the relay swap don't work.

Good luck

2005 gmc yukon back passenger doors will not unlock with key remote and rear hatch wont unlock or open


Either the relay for the locks is bad or the fuse. When you push the power lock on the inside if the doors do not unlock then I would check the fuses, both inside and under the hood. If they do work then the relay/s may be bad. You are pushing your key button twice correct?
