Driverside door control panel

All 4 window switches dead (including window lock), I checked the fusebox under rear seat - not the problem as the passenger window worked when I swapped the fuse into the passenger side fuse.

Wife left driver window open last night and it rained - I'm assuming this caused the issue.

What's your best guess at problem/solution?

Cheers!

Pop the control panel off, unplug the wires and hit them with a hairdryer. You've got nothing to lose but a little time investment.

I would imagine it will dry out on its own. I had the same problem with my truck and I couldn't wait for it to dry. I dipped mine in rubbing alchohol to help speed up the process. I'm not reccommending this to you. That is your call not mine. I would opt for the hairdryer. the switch isn't cheap but it isn't too high priced either if it is shot.

good luck.....I'm sure someone else will chime in any minute, maybe a better solution out there.

Electrical contact cleaner would be a way to go as well.

WD-40 will get rid of any water (WD = water displacement)

Bringing this thread back up as mine just died this morning. Along with the window switches all being dead, the door lock switch, seat heater switches, and mirror control are all out. Everything electrical in the driver's door is dead, the lights are out as well.

It rained a little bit while the windows were open a few days ago, but its been fine since then until just today.

The plug-in going from the chassis to the door is snug and tight.

The other window switches and motors work fine. So do all the door locks.

If I pull the door panel off, is there a circuit board that controls all of these items that might be blown? Is there maybe just a single fuse that controls just this door's electrical equipment? I just got this TB a few months ago so I haven't learned all the quirks.

I'll try the hairdryer thing but I'm thinking there's something else more serious wrong with it.

OK, so I got a new (used) control switch panel from someone on ebay. The switches for all of the passenger door windows work fine, so does the door lock switch. But the heated seat controls don't work, neither does the window lock button. And now, the most confusing thing, the driver's window switch only causes the window to go up or down by a few millimeters each time you push it.

Ideas? I'm trying to figure out if this "new" switch is also defective and if I should be getting in contact with the seller about returning it or if it is something else within the vehicle.

OK, check that, the seat heater switch(es) work fine. I disconnected the battery for about an hour to reset the electronics so it can "learn" the new DDM, but still having the same problem with the driver's window and the window lock button.

Any advice or ideas would be appreciated.

There is a GM Recall for the drivers side door switches. Water gets in and can cause them to not work and in a worst case cause a fire. I think the recall went out last June??? The thread above is 4 years old.
