1999 Ford Taurus 6 cyl Front Wheel Drive Automatic 120xxx miles
If I put the heater on in any position both radiator cooling fans come on. I noticed the ac compressor is also cycling on and off. The only position of the heater switch which the fans don't run is the vent position. With both fans running the engine temperature never gets up to the cold mark on the temperature guage.
Is this a problem with the heater control switch or is there a faulty relay causing this?
I'm changing the thermostat today because even with the fans not running the engine does not warm up.
Really greatful for you web site. Always find good help here. Keep up the good work.
