I determined last night that my electric radiator fan on my 2001 A6 4.2 doesn't work (gave 12v to both fans, A/C fan works, other is stone dead), and I'd like to find a new or good used replacement.

Since the radiator fan was dead and the A/C fan only spins at top speed, I'm thinking my module might be bad. Does anyone have any good tests for the fan control module? If I decide to run two electric radiator fans, will I need the Allroad control module instead?

Also, are there any good drop-in electric fans to replace the belt-driven clutch fan? I know the allroad came equipped with one, but I'm unaware of whether or not it will easily bolt into the shroud. Thanks to anyone who can shed some light on this. I've never had any problems overheating except when sitting still on the hottest days of the summer, but I'd like to take care of it now so it's not a problem next summer.

Sounds like your module is bad. I'll bet your other electric fan shorted or hung up as it failed and overloaded the module, causing the module to "default" to the jet turbine mode. Mine did when the rubber strip wrapped itself around the fan.

I personally would just replace both the fan and module, if only to get rid of the screaming fan.

Well crap, that's a bummer. What piece of rubber is it to which people refer? I've heard that a few times but it's never been clearly explained.

Also, what about the allroad fans?
