Subject: Re: [E36M3] E36M3 Window/Sunroof Failure


You might want to check the comfort relay on your car. The cold solder joints inside this relay have been known to crack causing intermittent or total failure of the window and sunroof controls. The relay is located under the drivers side knee panel. The relay itself is near the steering column under (above) the knee panel fascia and is Blue in color (approx 1"X1"X1.5"). The part number for the relay as installed in the 98 M3 is 61 35 8 364 690 (list price $20.18). From my recollection the relay is next to a couple of other relays that are mounted in a black plastic bracket next to the left side of the steering column. Be sure to use a flashlight as you may encounter several relays and much darkness. However, there is only one relay in the area of the steering column that has 5 pins and is blue in color. Upon close inspection of the relay internals you should find cracked solder joints where the actual relay is soldered to the printed circuit board. If you do find the relay and open it up and find cracked solder joints touch up all of the solder joints with a soldering iron and additional solder. Run a test before re-assembly.

Good luck
