my first gmc ever, need to understand how the a/c works or if there's a problem.
2006 sierra work truck....a/c is frigid cold, no complaints.
I dont hear the a/c compressor cycling so I press the snowflake button thinking it will deenergize the clutch circuit but the compressor keeps running.
I notice that pressing the recirculate to fresh air turns the compressor off. If the compressor does not cycle, how does it defrost?
Do I have a problem?
