Driver Window

Guys,
My locks were acting funny for some time, locking / unlocking on their own while driving, one day the driver window won't go up...no clicking and no power, so the driver side mirror and the lock won't work

I see the light comes own for the side mirror but the mirror won't move, I can lock / unlock all doors from the master switch except for the driver side. Remote control can lock/unlock all doors except for the driver side.

I tried two used master switches without any luck, fuse # 5 is good.

all wires seems to be tight and no visible cuts. any other suggestion?

- Probably bad lock actuator.

- Re window, search forum for the $5 plastic sliding clips...

I don't hear any clicking or motor movements when pressing the driver button. It seems to be no power is getting to all of the
1- driver side mirror
2- driver side lock
3- driver side window

I see power on the master switch, right side works or the driver rear window

Since you don't hear the window motor moving and there is an erratic lock, maybe check wiring connectors for corrosion as a cheap check. Spray some contact cleaner. Then re-check the fuse in case a loose connection caused it to blow after you checked. Bad lock actuator might also go up/down erratically when you slam the door shut.

After this, then it would go to wire continuity tracing, starting with the grounds since there could be shared ground points (grouping) for the door electronics.

By master switch you mean you replaced the whole module with the buttons on the door ? The fuse for the other door is fine as well ? Same as above, look with a flashlight inside the connector for corrosion ? Were all locks acting or just driver's one ? If all that may indeed point at the dr door module. Perhaps also try remove the alarm siren fuse and do a reset with the key fob (lock-unlock dr door 3 times). Another lead is maybe the reverse mirror, it has inside the receptor for the key fob

only the driver lock was acting funny, locking / unlocking on its own when I was driving before going dead. The original master switch (whole module with buttons) was replaced with another used working one from eBay from the same year, I can hit the driver side mirror button and the light will come on, when using the little gear to move the mirror it won't move, now if I click on the right side mirror button, its green light will come on and i can move it just fine. The same thing apply to the rest of the windows and their locks.

tried to reverse fuse # 5 with #6 but it didn't do anything, so its not the fuse, not sure if there is a relay under the hood that i need to test? but I doubt a relay will control only the functionality of the driver door and not the whole master switch.

I opened up the old module and i didn't see any swollen capacitors nothing fishy, can I spray it with WD40?
