I've been without AC here in NC for over a year because I swapped in a bad AC clutch which melted the solenoid. After installing the new replacement clutch, my A/C was not working at all, so I was close to resigning to taking to a shop to swap out the whole compressor. When I found your video, I double checked all of the fuses and sure enough, the A/C compressor fuse was blown. Swapped it out, A/C works beautifully now. So thank you!
AC worked great when last used 5 days ago. Today compressor comes on and the tubes get cold but the compressor does not stay on long enough, turns off then comes back on, never cooling enough. Suspecting freon but the Air was ice cold when last used. .?
What does it mean when the driver side ac starts blowing heat but the passenger side stays blowing cool while both set on cold,I have to pull over turn off car then restart for it to reset!
Hey, Thanks for this. Found out the AC relay was bad by replacing it with the horn relay and AC worked perfect. Now just need to buy a new relay. Saved me a more expensive trip to the mechanic…..kudos sir.
I liked the part explaining that the computer won't allow a'c to work if check engine light is on. Mines been on for 3 years but an additional problem could have caused it to come on again and since it's been on, I wouldn't know. Lot's of good info for such a short video.
Thank you, I tapped my relay it came on. I though it was because it was because the freon was too low, I let some out the other day and it stopped working after that. I swapped the wiper and AC relay foe the time being I will see if my wipers stop now... I do have a slow feon leak that requires me to top it off every so often. Appreciate the video and help...
Great video! My AC has been giving me issues and now I don’t feel the compressor turning on. Will start here. Thanks for the clear video with good visuals.
Nice video man, I’ll check my fuses because I got in a new compressor but only the back vents blow cold air now and the driver and passenger vents blow normal air, with your video give me an idea where to start looking
Having this problem at the moment, nothing was working then switched the horn relay with ac relay and the air started blowing but it was fuming hot and still no power to the actual snowflake button or any other buttons? Anybody know anything?

Now this is how you do a video! No added nonsense straight to core content. Thank you!

It’s the “ac actuator.”Super simple to fix. Purchase part on amazon.
@@realfaithlife2104 thank you!
Thas happening on my 2005 yukon .thanks
Yup! It's the blend door actuator. Had that happen on my '04 Sierra and a new actuator and caliberation fixed it.
@@nateb4114 How did you calibrate it?

Plug ac relay into horn slot and honk the horn to test it also😊
