Power Door Locks System Components
The power lock system consists of the following components:
• Body control module (BCM)
• Driver door lock cylinder switch
• Front passenger door lock cylinder switch
• Driver door lock switch
• Front passenger door lock switch
• Door lock actuators in each of the doors
• DR LK Fuse 20-amp
Door Lock System Controls
The Power Door Lock System is controlled by the body control module (BCM) and can be activated by any one of the following:
• A door lock switch lock or unlock actuation
• A door lock cylinder switch unlock actuation
• A keyless entry transmitter actuation
• An automatic door lock actuation (Personalization function)
• An automatic door unlock actuation (Personalization function)
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.
Driver Door Unlock Operation
When the body control module (BCM) detects a transition of either of the door lock switches to the unlock position, it switches the driver door lock actuator unlock control circuit to voltage. Since the door lock actuator lock control circuit is at ground potential within the BCM, the left front (LF) door lock actuator motor transitions to the Unlock position.
The driver door lock actuator unlock control circuit is a dedicated control circuit used only for the driver door lock actuator motor. This is done so that the driver door may be unlocked by itself using a keyless entry transmitter or an automatic door unlock function (if programmed).
Passenger Door Unlock Operation
When the body control module (BCM) detects a transition of either of the door lock switches to the unlock position, it switches the door lock actuator unlock control circuits to voltage. Since the door lock actuator lock control circuit is at ground potential within the BCM, the passenger door lock actuator motors transition to the unlock position.
The door lock actuator unlock control circuits are dedicated control circuits used only for the passenger door lock actuator motors. This is done so that the driver door may be unlocked separate from the passenger doors using a keyless entry transmitter or an automatic door unlock function (if programmed).

Power Door Lock Operation
The vehicle is equipped with power door locks. Each lock actuator is powered and controlled by the door module mounted in the individual door, but the rear integration module (RIM), which is the master control for the door lock system, determines when the lock functions are permitted. The RIM receives and examines the requested lock function from the individual door modules, or from the remote function actuator (RFA) via the class 2 serial data circuit. The RIM also examines the transmission shift selector position and the ignition switch position information available over the Class 2 serial data circuits. If the RIM determines that a lock or unlock function is permitted, it sends a class 2 message back to the individual door modules commanding them to perform that Lock or Unlock function.

This is an easy and quick way to fix a lock on a 1989 - 1993chevy truck! ... 1985 Chevy C30 Power Door LockTroubleshooting & Repair ...

My 2009 Sebring does the same thing occasionally but only the drivers door gets stuck (dead locked - even though the locks appear to pop up).
The solution I have found once this happens is:
1) The car needs to be driven (crawl in thru the passenger door) -even just a short distance
2) Engine shut off & doors locked with remote (after you've exited from the passenger door of course)
3) Leave turned off for 10 minutes
4) Doors will now open when unlocked with the remote

Sounds like you have more than one problem.
The seat belt light is not on because of the door.
Are you saying the serpentine belt comes off the engine pulleys ?
And have you checked the battery and starter for voltage ? You need 12 volts at the battery and at the starter, and on the small wire from the starter to the key switch.

The rear doors probably dont come w accuators in them. Meaning that the rear doors alot of times don't have power options. If you are certain that your rear doors have factory power locks then I would say it's a wire somewhere...did you try a double click of the unlock button. My two door chevy truck unlocks the driver door with one click and the pass door requires a double click. Hope this helps !

front doors will lock & unlock with key but they wont open with the door handles on both doors .are you sure they are unlocking?

I really hope help you with this (remember rated this help). Good luck.

From the back of the front door slide your hand in the sliding door crack and find the child-safety-lever. Push the lever up and/or down while moving the sliding door manual lock/unlock button to the up position. Also works on the non-powered sliding door.
