1993 Taurus GL A/C problem
a couple of years ago i took my car to an A/C guy that replaced the compressor as the old one had a worn clutch. i did notice after he fixed it that he added a relay that activates the main radiator fan when the a/c is turned on. until today it worked ok. now it seems the relay is bad as it keep the fan working always. i disconnected it to avoid dead battery.
my question is - why is this relay needed ? dont the car "know"to operate the fan more often when i turn on the a/c ? or keep it working at minimum speed as long as the a/ is on ?
Thanks for any help !!
