My low and high fan speed pressure sensors in the condensor are faulty, they run all the time, with the AC off, when the car is cold in the morning. thats ,must be why I found them unplugged. Until I can replace them I tapped into the compressor signal line with the coil of a relay. The coil draws 225 mA I then ran the wires for the low speed pressrue sw through the normally open contacts of the relay. Now the fan is on whenever the copressor is on OR whenever the radiator temp switch says it time. Will the small current draw of the coil have any effect on the existing circuitry. Will having the fan on on the highway bring diminishing returns in terms of cooling efficiency.


thanks,

Matt
