RE: Audi 80 radiator fan doesnt turn on
I am not familiar with the 80 series but I would suspect that the relay panel is somewhere under the hood next to the firewall. The cooling fan system is somewhat similar on the 4000S and 1CQ so it should be similar on the 80 as well. First does the fan spin if you turn it by hand, if it does you can try jumping the relay if it is stuck don’t even think about it. Jumping the relay is somewhat tricky and I would recommend that someone who is more knowledgeable do this. The relay has four prongs, two are the coil and two are the switching contacts. The terminals will be numbered 30, 85, 86, 87 or maybe even 87a. You will need to make a short "jumper" made out of two .25" male blade connectors and 12 or 14 gauge wire. You want to inset the jumpers across the switching contacts on the relay socket. I believe these are numbered 30 and 87 or 30 and 87a, the fan should turn on right away even with the ignition off. The fan draws a lot of current so some arcing will be present when you insert and remove the jumper. If doesn't turn on try it with the ignition on, if it still doesn’t turn on then the problem will need further troubleshooting. It could be the fan.
