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 disconnecting the battery for a minute but still the same problem. Any solutions?

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 .

SOURCE: 2006 Chevy Equinox

Hiya...the factory-installed keyless remote control are installed in most Equinoxes IF SO equipped with this option that year.
However, it's difficult to get "true factory-installed" keyless feature in your Equinox ....but new 2008-2009 Equinoxes built this year now comes with standard keyless remote and yes, new option is remote STARTER feature (that option is identified by a black wire found inside the rear-right quarter window with thin metal line surrounding that interior window to receive signal from remote starter fob)

At least you can find after-market keyless remote control at your local retail store.

SOURCE: Replacing Passenger Window Motor

Just replaced 2004 passenger side motor. Bought motor/gearbox for 31 dollars, free shiping on line, removed motor and regulator , looks like a guide with cables, leaving it all together. We taped window at top and used a pair of small vice grips to clamp the small cable to the frame so it wouldn't move . As we removed the 3 small screws holding the motor/gearbox in place , it slips out showing it has a large plastic spline gear slightly visible . We used a small screw driver to seperate the gear/motor from what looks like a barrell with that cable wrapped around it. We were careful
not to let this cable drum get loose, so we made sure one person held it inside the housing. Slipped the new drive in and done with that. No one mentioned there was a bracket holding the door panel and I had to pop out the manual lock button to access a small screw, don't drop that screw down insde the door, would be hard to get out. I didn't have to make any adjustment and it works great.

SOURCE: 1998 Chevy Camaro - security

My camaro do the same, think i paid round 40 for a replacement remote. With all doors closed try cycling the ingitoin 9 times to reset the light. This might help you bypass and disable the alarm. Turn the key to the run position, off postiton and remove the MAIN RADIO FUSE, than turn to acc position.after you done that hit the door UNLOCK switch until it CHIME ONCE, the alarm system should be off/disable. Turn the ignition to the off position and put the RADIO fuse back in. Hopes this helps

There is a control module in each door with connectors. I have already had one where the wiring in the connector was bad. This takes some troubleshooting, but sometimes moving things around while trying to run the windows will should you where the loose connection is.

The door lock on driver side front doesn't work anymore with the remote, the other doors are working fine on a Lincoln Ls 2004

Try using the Keyless Entry Pad

If that won't open the drivers door,
then you will need a scan tool, to see
if it can comunicate with the DDM -
Drivers Door Module.

That may be a possible problem, if
everything else works

Good afternoon....what would cause my 2008 Chevy

It could be the power lock motor. You could have a short or bad wiring harness. Might just be a fuse that connects to both. But since you said it's only the driver side. When the power lock motor is bad it can trigger your alarm because they're wired together.

Hope that helps. Good luck.

My 2002 chevy astro van power door locks are not working. Only the drivers side door will open with the keyless entry. Pushing the unlock button inside the van still won't release the other locks. What can...

i can help , kinda, i had trouble with my astro van door lock in the back , it is not connected to the electric door locks , turns out the thing was broke inside, i had to pry off the inside panel and reach inside the door itself to unlock it, this can be done without damaging the panel or trim but you have to unscrew some parts, and work it loose very gently, on the rest of it, well i have been having trouble with the door locks on my astro, i think its just a weakness in design on these guys
