Folks,
I'm trying to fix not working Cooling Fan.
Found Fred's post in archives but wanted to clarify something.
I have same thing - +12 on both relays which means fuse ok. I did not try to
jump terminals yet, but wanted to get prepared for checking resistor pack.
Does anybody know exact location of this thing? I don't even know what
should it look like :)
Any easier way to get to it then to remove bumper and intercooler? May be FL
headlight will do?
Thanks,
Ivan

Your fan relays are in the relay box under the hood, drivers side. There is
a resistor pack mounted down by the intercooler somewhere. When I had this
problem on my '94 S4 the fan harness connector was burnt - you have to
remove the front bumper and intercooler to get to the connector. Well, you
don't have to do that on my car - now :o).
I narrowed down my problem by pulling the Stage 3 relay and checking for
power feed - there was power, so the fan fuse & power feed circuit was OK. I
then shorted out the power terminals in the relay socket with a jumper - the
fan still didn't run, so the relay circuitry and resistor pack were not the
problem. That left the motor and the harness, so I checked the harness first
and found the burnt connector.
