96 3500 454 reg cab

Hey, this is charged with freon, just wonder what to check.

I have seen High Pres. switches ( On the accumulator ? ) go bad.

I dont remember what else to check for power or to jump to bypass stuff. Any help would be great.

Oh yea its my brother inlaws truck

How do you know its charged?

jump the pressure switch on the accumalator to see if the ac cycles on. Might also check under the hood for the ac relay to make sure it is good, and natrually fuses etc. Can you see the clutch to make sure the connector is hooked up? I think those still had the A-6 compressor and the plug on some of those would get hot and melt also check the clutch to make sure it is not fried. double check the charge.
