In my '87 Cabriolet when I turn the heat on, the radiator fan comes on - is this correct? Something tells me it didn't always do this, but my memory is going and can't say for sure.

Re: Radiator/Engine fan comes on with the heat. (skowsa)

i think it's supposed to come on when the defroster is turned on, something to do with compensating for the extra heat generated by the ac compressor working. should come on the the ac too.

vwuberalles is correct on that. never heard of any carthat the radiator fan kicked on with the heater, u probably have a switch bad in the climate control system
