94 Grand Am Power Lock - front drivers side door (Trying again)

All the other door locks work, but the drivers side front door does not lock or unlock with the switch.
I CAN hear the noise in that door indicating that it's trying, so I'm guessing that the switch works, but the actual lock does not move.

I'm wondering if the rod is out of location with the switch or something? I've just replaced the power window motor so the door panel is currently still off. I would like to get the lock working right before replacing the panel. The problem is that I don't know how to do this. How does the rod hook up to the mechanism?
Any suggestions?

First, I'd recommend buying (or borrowing from the library) a Chilton or Haynes Manual to help finding the parts and how to access them. They'll save you a lot of time and headaches.

Then I'd try replacing the door lock motor. The motor itself should be just behind the inside door panel. Many times these motors, after years of wear and tear, break the teeth off the internal gears, causing a loud grinding/whirring noise but not allowing the doors to fully lock or even lock at all.

You can either buy a new motor from an auto parts store, but I've found that by checking with the local junk yard turns up some really good deals. Try to find a car that is the same make and model but maybe a newer year, bring the old motor with you, and make sure they look exactly the same down to the mounting holes.

I hope I could help you fix this issue. Good luck and don't forget to rate! Thank you!

Drive side power door lock is not working

If the door lock works ok with a key, I would say the lock actuator is failing. Its a small electric solenoid that moves the lock rod.

I have a 08 chevy avalanche the driver side front and rear door locks won't work when I use my keyless entry button or on the inside driver panel. Could it be a fuse? Passenger side works fine I try...

Do the power windows work ? DDM - driver door module fuse 15 amp - location is the instrument panel fuse box , plus LT DR circuit breaker 25 amp. Circuit breakers rarely go bad . The power locks are controlled by electronic's .The passenger side has another power supply ,that's why they still work .
Door Lock System Components
The power door lock system consists of the following components:
• The driver door switch (DDS)
• The passenger door switch (PDS)
• The body control module (BCM)
• The driver information center (DIC)
• The rear door lock/unlock relay (LBEC)
• The reversible door lock actuators in each of the doors and liftgate

The front power door lock switches are integral components of the driver door module (DDS) and passenger door module (PDS). The switches are 2 position normally open rocker switches. When placed in either the lock or unlock positions, the switches provide a direct input to the DDS or PDS. The DDS or PDS monitors these inputs and sends a LAN message indicating a change in the switch's respective position. Modules which activate the power door lock motors receive the LAN message and activate the motor in the appropriate direction to lock or unlock the vehicle's doors and liftgate. The rear door lock switch provides a lock and unlock signal to the body control module (BCM). The BCM upon receipt of a lock or unlock signal will control the rear door lock/unlock relay and also send a LAN message to the DDS and PDS to perform the appropriate function.
The modules which activate the power lock motors are:
• The DDS (driver door lock actuator)
• The PDS (passenger front door lock actuator)
• The BCM (both rear door lock actuators and cargo door/liftgate)
The DDS and PDS are directly connected to the respective door lock actuator through the door lock motor lock and unlock circuits. Once a door lock or unlock request has been received, the module will supply battery voltage to one side of the actuator and ground the other causing the doors to lock or unlock.
The rear passenger and endgate doors are controlled by the BCM through the rear door lock/unlock relay which is incorporated onto the printed circuit board in the LH BEC. The BCM controls the unlock relay by providing ground to energize the coil and controls the lock relay by providing battery voltage to energize the relay coil. The energized the relay and allows voltage to be applied to either the door lock motor lock or unlock circuits. Since the other side of the door lock actuator is connected to the normally closed contacts of the opposing relay to ground, the doors lock or unlock.

It's possible you have broken wire or wires inside the flex boot from the body of the vehicle to the driver's door . This happens a lot .

Hi, Somehow the boot of the car has locked

All locking and unlocking is done through the switch on the drivers door lock. Put the key in the drivers door and lock and unlock several times. See if the boot opens then.
Or make sure you haven't hit the lockout button on the drivers door that stops anyone else from opening their doors. (Including the boot.)

Jeep grand cherokee central locking system

If all the doors do not lock or unlock when using the passenger side switch, then the switch itself is probably bad.   If the passenger side switch locks or unlocks all the other doors except for its own, then the power lock solenoid inside the door is bad or jammed.  If it is jammed, try locking and unlocking the door manually while activating the switch to work its way free.

94 Grand Am Power Lock - front drivers side door not working

Sounds like you are right. If it has ever been unlocked with a slim jim, it could have pulled it loose. You have to remove the door panel to get to it.
