Okay, to start off I have an 02 1.8t. Over time, I have noticed almost a "glitch" in my windows when using the master switch on the drivers door, and it has gotten progressively worse. Now, the drivers as well as both rear windows, when the button on the master switch is held down, go down a little, stop, go down a little more, stop, on and on. When using the master switch I get no reaction at all from the passenger window, it just stays up. When I use the back window buttons on the back doors, they work fine, and the passenger sometimes goes down, but not all the time, which is weird. When it does go down, it goes down nice and smooth as it should.
-On top of this, my passenger power mirror is not working.
-When locking/unlocking doors with fob or master switch, passenger door does not respond. There is a "click" sound while using the fob, but nothing when using the switch. The switch on the passenger door unlocks/locks the passenger door as it is supposed to.

Mechanic said it could possibly be a short in the switch on the drivers door, but that doesn't explain the issues with the passenger door itself. He said to also check out the CCM for damage.

Pulled up the carpet and checked all wiring/grounds around CCM, and everything shows no sign of water or any other damage whatsoever (woohoo!)
Pulled off panel in passenger footwell and checked all wiring going into the passenger door, and again, no sign of any damage/corrosion.
Pulled passenger door panel off and checked wire harness going into window motor, and all appears well with it.

Could it be the switch as well as something else? Possibly the wiring harness into the window motor? I've checked almost everything and I'm out of ideas.

Thanks to all!

It looks like you do have a faulty switch and other faults; as always, you should start with a VCDS scan and post the codes.

Check the wires and connectors between the doors and pillars, and see these links.


NOTE: The car in this DIY is UK RHD. (the CCM is always on LHS)

With this being kind of stupid cheap, I'd just replace with another switch and see if that's the fix.

I'd also check the area between the door and the frame where the wires pass through. It's a rubber accordion looking thing by the door hinges. On earlier models, the rear doors suffered from VW using a harness that was just slightly too short which caused the wiring insulation to crack and the eventual break of a wire.

If your car battery has any age on it...3 years or more...I'd get the battery tested. Our 2003 Passat was having weird door lock & window issues. I doubted it had anything to do with it, but the battery ended up testing bad, replaced it, and the electrical gremlins went away.

Okay, so I took off the rubber boot about 5 days ago and inspected the wires in/around the area, all appear well. Went out to drive today and my fob wouldn't work, opened the door and noticed the clock and mileage screens were blank. Turned the key and no sound at all. Jumped it, drove to the autoparts store, and the little machine diagnosed me with a dead alternator. Swung by another store on the way, same result. Could this be related?
