Question about 1995 Chevrolet Suburban

1996 Chevy Suburban Electric Locks

The driver side door lock is the only fully functional lock. The other three switches only have locking capability, but do not unlock. The drivers side switch will only lock the other three as well. There is a 12v signal going to the lock switchs when using the lock and unlock positions, but the locks only respond to locking position.

    I have the same problem on the same vehicle. It just happened one afternoon - in the am was OK. Looking through the schematics there is ONLY one way this can occur - -bad connection at a splice (# 258).

    This splice connects the output from the door relay to rf, lr, rr, cargo doors AND the remote module. The remote module in turn then unlocks ONLY the lf door. Obviously the relay works, the remote module works and the connections to the remote module are OK. --otherwise the LF door wouldn't work.

    Unfortunately, I can't find the splice and there isn't a lot of room under the dash -- I'm toying with taking it a aprt, but..

    Anyone have ideas wold be great.

It might be that driver side control unit. They've been reported to have problems with short circuits (even mine has had problems) Check fuses. However, a junkyard is probably the only hope for finding those relays -GM generally doesn't make them anymore.

Lock an unlock by them selves ? Door locks are computer controlled ,by the BCM - body control module .
--------------------------------------------------------------------------------
Power Door Locks Circuit Description
The power door lock system includes the following components:
• The door lock actuators
• A door lock relay
• An door unlock relay
• A driver door unlock relay
• The door lock and side window switches
• The body control module (BCM)
• The endgate lock cylinder switch /liftgate lock cylinder switch (utility)
• The keyless entry, if equipped
The door lock and liftgate mechanisms may be controlled by the following switches:
• The door lock and side window switches
• The BCM
• The endgate lock cylinder switch / liftgate lock cylinder switch (utility)
• The keyless entry, if equipped
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.
• The lockout prevention -- This function will prevent the doors from automatically locking if the keys have been left in the ignition and the power door lock switch is operated.
The motor is protected by a built-in electronic circuit breaker (ECB). If the motor is overloaded or voltage is applied for an excessive amount of time, the ECB internal resistance increases, essentially creating an open circuit. The resistance returns to normal only after voltage is removed from the circuit, thereby restoring circuit continuity.

You have a bad switch input to the BCM !

to see if it is a switch problem see if the locks work from their respective doors, if the locks work from the switch's on the back doors and not from the drivers switch then the drivers switch is bad. If the locks don't work right from any of the switches then the door lock solenoids are bad. the solenoids are not too hard to change if you are mechanically inclined, switches are not too hard either

Where is the fuse for the door locks on a 1996 chevy 1500 series


For 1996 Chevrolet 1500, the fuse block door access is on the drivers side edge of the instrument panel. Pull off the cover to cover to access the fuse block. Check the position 13 (Power Amp, Cigarette Lighter, Door lock Relay, Power Lumbar Seat) and A position (Power Door lock, Six-way Power Seat, Keyless Entry Module).

Other details can find in the 1996 Chevrolet 1500 - Owners Manual

Hope this help (remember rated this help).

All of the door locks but one on our 1999 GMC Suburban will not lock or unlock when using either the remote or the door lock switch. Is there a relay that accuates the locks?


there is a relay but if it were bad none of your locks would work. your problem is the door lock motor it is a little electric motor that actuates the lock. its also called a door lock actuator. kind of expensive and a little difficult to replace.

1996 saturn door locks have stopped working on the inside


If they are electric locks, you could have a bad switch in the drivers door.  I had a similar problem.  The locks made a noise from time to time like they were rapidly locking and unlocking for 5 seconds at a time.  I replaced the toggle switch (lock/unlock) in the door and that fixed the problem.
