Q: A/C blowing hot air
My a/c just started to blow hot air, I was driving and it went from running cold to warm. I have checked the relay, but the clutch is not engaging and obviously the compressor is not running. My question is if the system has run completely out of refrigerant and tripped the low pressure safety switch or the switch is faulty, how can I get the compressor to kick on so I can get a reading on the refrigerant pressure and possibly fill it if it is empty?
