A/C Condensor Fan Operation
Hey everyone Question about your condensor fan operation on the 1997 D90(don't think the 94-95 is the same cause the fan is triggered by the ecu reciving a ground signal, but i could be wrong). I replaced mine because it was frozen up. Now when the a/c is on, according to the wsm, the condensor fan should be running. But if you read the info about the circuit operation thru the trinary switch, it says the contacts close above 305psi on the high side. Trying to figure out if the trinary switch is bad, or if the condensor fan only runs when the vehicle is hot and pressure is really high...I know it is supposed to kick in if the engine overheats. Anyone who would take the time to verify whether their fan runs everytime the a/c is on or just when needed would be appreciated...The fan runs once in a while on mine....
