Radiator fan always on after AC fix
Audi 5000 S wagon 1987: AC didn't work properly, the guy removed the relay that controlled it (probably wired it directly); now AC works OK but the radiator fan starts working as soon as I turn on the ignition and keeps going all the time until I switch off. Is there any way to get it to work as it should - only when the engine's temp. is above a certain level? Thanks.

Re: Radiator fan always on after AC fix
The fan is supposed to run any time the A/C is engaged. It pulls fresh air across the A/C condensor in front of the radiator. Does the fan run when you turn off the A/C?

Yes it does run all the time
Actually, it didn't do that before the fix, when the AC worked occasionally, even then the fan went on only when the engine temp. went up. But now it's on the moment I turn on the ignition, even if the AC is off. So, does the AC use the same relay as the radiator fan?
