power windows/sunroof help

[wildinoutthug]

I have a 1992 325i auto.Im having problems with my windows and sunroof. I checked the fuses none are blown. Some symptoms are none of the windows move up or down, the window buttons aren't lit.......I've read that it could be my comfort relay....but not sure..is there any way to test the comfort relay ...if it is can someone explain where it is located and instructions on how to replace it..pictures would be appreciated...so any ideas or help will be really helpful.....thanks

you're proabably gunna wanna pull up some wiring schematics to find out where the relays and such are at so you can start trou8ble shooting...

i think the downloadable manual at the top of the forum has wiring diagrams
