Hi Eric, Thank you for your videos. My husband’s air will not work on his 2005 Chevy Colorado. I found other forums online and found a common problem where the resistor and wiring harness burn out. That was an issue. I’ve replaced it and the issue resolved for a while but air is out again. We then had the a/c charged, it worked for a while and is out again. What should I look into next? Thanks and stay dirty!
