85 UR quattro

Thanks to some tips from some helpful Audi owners I got into the door again yesterday. The switch does just pry out of the handle and is easy to unplug with the help of a screwdriver:

Then it was easy to get the door card off and find out what is causing my window to stick.

Here's one obvious issue. Two of the isolator studs that hold the motor to the door have sheared so the motor flops around under load. Can't be ideal.

Fortunately there was a threaded hole in the motor that lined up with the big hole that I assume was for a hand crank on lesser models. I used a big washer and secured it in place. I couldn't locate it where it wanted to be as it wouldn't clear the big aftermarker speaker that a previous owner added. maybe this is the cause of the shearing.

Hopefully that helps though the window still felt loose in its guides. To help I shoved some large cable ties behid the guides to push them out a bit and take up some of the slack. It work somewhat.

I tried to replace my rotor arm but was supplied with the wrong part. Hole is too small.

I did mange to find a self tapping screw to hold my hall sensor in place though. no more cable ties. Looks almost OE.

I had a go at my over-abundance of heated rear window switches too. I loosened the bezel but it wouldn't come off without removing the steering wheel and indicator stalks. Fortunately I still had enough room to pry out the switches and blank and this is what I found taped up:

Looks like someone nearly had a fire. This might explain the two HRW switches and why one was iffy. The undamaged one wasn't connected to anything nor were there any extra wires back there so I suspect a prevoius owner bought a new switch to try to fix a non-funtioning HRW and just left them both in place when he found the melted mess. Im not sure if I'm going to deal with this one either.

I am wondering if there is a short in the HRW wiring somewhere. I had a quick look in the under-hood fuse box but didn't find a relay for it.

Maybe one day when the dash is apart I'll splice in a new HRW connector for that newer switch.
