So I'm having some trouble with one of my windows, hoping for some advice on where to start looking. 2006 h3 adventure.

When the trouble started, the rear driver side window would intermittently not respond to the master panel (on driver door). It would roll down a little, then stop. Then not roll up, then suddenly would respond and roll up like normal. All the while it would work just fine with the controls on the back door. So this made me think I was having a problem with the master panel on drivers door. But now it wont respond at all to either the master panel, or the control on the back door, but heres where I get confused: If I press/pull the button on the master panel, the button itself will "stick" in place...If I pushed it down, it sticks down. If I pull it up, it sticks up (aka, the button itself doesnt naturally return to its "neutral" position like it should).

So if the problem is the master panel, why wont the window work with the back door control? But if the problem is the window motor, why would the button on the master panel be acting weird...? Could it be the motor, and the issue with the button is just a second problem thats coincidentally happened at the same time...?

Im not sure where to tear into first, any advice would be much appreciated.

P.S.- The other 3 windows work as normal, from drivers door or their respective doors controls.

 

Is it "sticking" as in there's something sticky like coke in there? Our windows are tiny and people are always spilling route 44s trying to get them in the truck. If there's crap in there it could be shorting out. You could unplug it and try to get some 97% isopropyl alcohol down into the switch and work it around. Let it dry/evaporate for a while before you plug it back in.

 

unplug the rear door connector and check it for crud or just plug in/out a few times to clean contacts.

a guess.
the front switches and back sw run the same 2 up/dn relays so it could be contacts not making conn,??
