Well I cant seem to get my Ac to work. All fuses are good, I checked the relay and that wasn't it, and I also charged the system...Still nothing. The compressor spins when the engine runs but I dont think It kicks on. Idk if your able to hear it or not when it does. Any thoughts?

 

I'm having the same problem and no one has answered my post. I hope someone out there has some ideas.

 

What year what style what's it doing

 

97 with a 5.4 xlt extended cab 4x4

 

Did it hold the charge ?? The compressor clutch should kick in and out as the system cycles...you can see and hear it work...it could also be over charged now. It will not work if under/over charged.

 

What do you mean the compressor spins? Does the clutch engage? Can you hear the AC engage when you turn it on? How did you charge it? With an AC machine or a bottle of 134A. How did you check the relay? Did you try swapping it with a known good one?

 

Charged it with 134a according to the Hayes manual. I cant hear anything engage.

 

Just to make sure have someone turn the AC on while your under the hood and if the clutch engages its a distinct noise like something's turning on if it doesn't sound like anything then it's the clutch frozen or a bad relay

 

Sometimes the clutch can go out on them aswell... We normally would give the Compresser a few solid tapes with screw driver while the truck is running... If it kicks on i would say thats a dead give away its the clutch.
