Front door locks

Service repair info. manual would be the place to start ,seeing how you have no clue .,or maybe a qualified repair shop. How are you going to fix it with out knowledge of how it works an what to check , --------------------------------------------------------------------------------
Power Door Locks Circuit Description
The power door locks are operated by reversible motors. The motors are found in the following locations:
• In each front door
• The side door
• The rear door
The PWR ACCY circuit breaker (30A) supplies voltage to the door lock motors.
If you move either power door lock switch, mounted in the front doors, the LOCK applies voltage to cavity F of the door lock relay. This energizes the lock coil in the relay. Current then flows through CKT 295 (GRY) directly to the following components:
• Both front door lock motors
• The side door lock motor
• The rear door lock motor (cargo doors only)
CKT 246/294 (TAN) provides the ground for the motors. The normally closed contacts of the UNLOCK then contacts the door lock relay.
If you move one of the door lock switches to UNLOCK the polarity of the system reverses. Current flows through the energized UNLOCK relay contacts. The LOCK relay contacts provide ground.
When the UNLOCK button is pressed once on the RKE transmitter, only the driver door unlocks. If it is pressed a second time within 5 seconds, all doors unlock.
If the side door is open, the side door jamb switch ground signal is opened/broken. If you move the door lock switch to LOCK while the side door is open, the following actions occur:
• The 2 front doors lock
• The rear door locks (cargo doors only)
When you close the side door, the door jamb switch closes. This closes the ground signal to the body control module {CKT 775 (PNK)}. A 5 second timer then starts in the module. After 5 seconds, cavity A4 connector C1 of the body control module supplies voltage to the door lock relay via CKT 195 (LT BLU). This energizes the door lock relay, which sends voltage to the door lock motors in order to lock the side door. Refer to Door Jamb Switches, Liftgate Strut Switch for a schematic of all door jamb switch inputs.
If the side door opens during this 5 seconds, the 5 seconds timer is reset. The locking pulse takes place at the end of the 5 seconds. Unlocking the door resets the 5 second timer in the body control module.
Use the following components in order to unlock the door lock system:
• The LH power door lock switch
• The RH power door lock switch
On vehicles equipped with cargo doors, the cargo door opener mechanically opens the door once the door lock system is unlocked. On vehicle equipped with a liftgate, the liftgate lock/unlock release switch (mechanical key) is added in order to serve the same function as the front power door lock switches. These functions locking and unlocking all doors, including the liftgate. Once the door lock system is unlocked, press the liftgate release switch in order to electrically open the liftgate and pull the handle in order to open the secondary latch.

If the door buzzer switch is broken and moving around it will ground out on the door an complete the circuit and cause the buzzer to go off. if you do not want to fix the switch remove the wire from the switch and tape it up with electrical tape

Open the inside panel of the door by popping off the little white clips holding it on. The cable connected to the inside release button is either caught on something or has come lose. Check out this video - https://www.youtube.com/watch?v=MkC2OiOiE_U

Same thing happened with mine. It turned out that the power door lock motor went out. Since the handle or the switch can unlock the driver's door, both of these mechanisms are connected. When the door lock motor goes out it freezes in whatever position, it was last engaged.

possible bad actuator ,wiring/connection problem,switch,actuator rod disconnected[clip popped off or broke-u can test power to switch but for the others need to remove door panel to access the lock system

either something jammed in track/lock-- or actuator rod broke or disconnected from lock --need to remove interior door panel to get to lock release and latch check all rods and clips for damage or missing repair or replace as necessary u can manually unlock the door at latch if something was jammed or stuck in latch

if it moves even a little bit when the button is pushed it wont be a fuse issue, you more than likely have a weak door lock actuator

open the door and look on the side of door for little switch up and down ,it a safety switch ,little gray lever sticking out on the side of doors, move it up or down ,read decal on the door jam,hope to help robert b.

the little motor that operates it inside the door is probably frozen, so it will need to be replaced!!

PULL THE DOOR OFF MAKE SURE THE 2 LITTLE DOOR HANGERS ARE CONNECTED TO THE SWITCH MECHANISM IF IT IS. THEN YOUR SWITCH IS BROKE. GO TO SCHUCKS AND ASK THEM IF THEY CAN ORDER YOU A WHOLE NEW DOOR LOCK SWITCH ASSEMBLY. REWIRE AND TAA-DA!!!
