1995 Audi 90 Quattro battery drain issue
Hello, I picked up an Audi 90 a while back and have been going through and fixing it up. I am struggling with an issue where the electronics won't turn off. I think it could be the relay for the windows and doors, but I am not sure.
Here is the issue: when I turn off the car and pull the key, I can still operate the windows (when they are working). I don't have any functioning lights in the cabin, but I noticed when I had the back seats down that the light in the trunk never shuts off. I also will have issues where the windows will stop working while I am driving. (This is annoying because the AC does not work. The fan does, but no temp control) First, I want to fix the window and lights issue because I think it is the reason the battery drains when I park the car. Then I'll try to fix the AC.
The previous owner did the LED fog lights, but as far as I am aware, they shouldn't be pulling on the battery, as they were wired into the factory fog light switch and relay. I haven't done a ton other than some suspension work since I bought it.
