Sunroof/moonroof dead - E36 318is
It started off working intermittently and now it does not work at all. Fuse us fine. I read some bullitins that pointed at the comfort relay. I checked the comfort relay (I opened up, and checked all the points for continuity with a multimeter) and it seems fine. I then checked the power cable going into the relay (thick Red one) - there does not appear to be any power going into it (even with ignition powered on). If I connect a wire to the battery and connect the other end directly to the comfort relay 'power in' wire, the roof now works.
The basic wiring diagram I have says that this wire goes back into the main fuse box again - the problem is - I cannot get the fuse box base open. I remove the 4 screws and it won't budge??
Any ideas or am I looking in the wrong place completly?
