Hi everybody hope you can help.
Focus 2002 1.6 Zetec

Every time I turn on the heater blower, even only on 1, the A/C condenser and both cooling fans kick in.

I haven't put the A/C on and it happens even when the engine's cold.

I've checked the fuses and they seem to be ok.

Its costing me a fortune in fuel when I want to de-mist the windscreen!!

Any ideas to what the problem might be?

Thanks

Pete
