Default Audi 4000 windshield wipers, power windows, heating fan stop working at the same time

Good day! Please help me to figure out electric issues. My power windows, windshield wipers blower fan and engine cooling fan stopped working at the same time. That has to be related some how. I don't know what to look for. All fuses look good. Thanks

Hi did you ever figure out your problem. I just got this exact issue with my 1986 Coupe GT. I bypassed the radiator fan with a switch inside the dash so I can turn it on to prevent overheating but everything else not working at the same time is weird. I tried so many things but came out with nothing. Hopefully you were able to discover something. Thanks.

Hello all,

Ignition switch contact "X" is not working or the relais that goes with it.

ciao

So the solution is to replace the ignition switch? What do you mean by contact "X" and is the relay in the fuse panel or the relay panel behind the dashboard or is there another place? Thank you for your help.

You might want to start in getting yourself the wiring diagrams. That will get you started in understanding. Use the search function here, it has been explained and discussed multiple times.
