Hey guys, but of newb question. When I bought my car the A/C was blowing ice cold. One day out of the blue the A/C stopped working. The compressor wouldn't engage. I jumped the switch for 15 seconds, compressor started and I had cold air. I didn't have time to check if the system had freon but my biggest concern has to do with the fan. If I select A/C is the fan supposed to turn on no matter what or only when the compressor engages? If I do a KOEO test the fan kicks on at both speeds when it starts the test. Thanks!
