ALL windows don't roll up or down

Join DateSep 2011LocationLafayette LouisianaPosts23My Carse36 m3

I have a 97" m3 sedan and for Christmas I got a new integrated radar detector that had to be installed in a "key off fuse" (so it turns off when the key is turned off) but the BMW fuses were much to wide so I thought to myself il just splice it into a wire under the dash. I just started testing a few random wires and a couple of sparks flew but eventually got it all hooked up and it works perfectly BUT All my windows don't work, the buttons are illuminated and when you press the button the motor doesn't click they do roll up when you hold the key in the lock position when locking the vehical. I have used the search function and everyone talks about a comfort relay which supposedly only works on 92-93 models(correct me if I'm wrong). I've checked all my fuses numerous times. The only fuse box I know of is under the hood, which number fuse should i check? Before I drive 30mins to the dealership I want to know if none has any advice.

the comfort relay is below the kick panel where the pedals are. It is on the left side and is blue. Do some research on that relay and you might be able to jump a few prongs to get some power to the windows.

Also, check the fuses again and make sure you didn't blow any of them. There should be a layout chart under the fuse box cover that will direct you to the correct fuse.

My car is doing the same thing, exact same symptoms. I also read about the lack of comfort relays on 96+ cars. The only thing I could thing of is that the ZKE module died. I picked one up on ebay and will try and replace it this weekend.

This site has a bunch of info on ZKE modules: http://www.bmwgm5.com/

I thought 92s were the only e36s with comfort relays.

OP shorted something. Testing wires and got some sparks...dude shorted something for certain.
