My S4 '98 developed a problem - radiator fan works non-stop. Today I
finally found time to look into it (I drive 200tqa '89 last 3 month).
Hooked up battery charger - it runs, unplugged radiator temp switch - it
runs. Left it unplugged. Removed relay 2 - it runs, plugged it
back. Removed relay 3 - it runs !!!! Looking at the electric schema
on the Bentley CD I am totallly puzzled. It shows two motors
actually. Is it 2 stators in one case? Anyway, they both are powered
through relays 2 and 3. I did not try to remove both relay at the same
time, but all sensors except radiator switch can close either one or
another relay and the rad. switch was unplugged. So, sequential removal
should be sufficient, according to the schema. Can it be that my car
has different wiring than CD?
