Im experiencing a problem with my a/c compressor. It's never engaging when I hit the button to turn it on. I stopped at a car shop yesterday and they told me it's charged with freon and that they think it is an electrical problem. Well since im an electrician not a mechanic I figured i might be able to trouble-shoot the problem. All fuses seemed to be ok by sight and checked good with my meter. The larger relay in the electrical box had continuity between two diagonal poles. Sorry for the length of the question, just trying to be informative. Thanks a lot, and I forgot to tell you it's a 2000 model chevrolet 1500 5.3 liter V8.

I have dual climate control and it has been blowing heated air out of the drivers side for some time now. I removed the blend door actuator that controls the drivers side. It appears there is a plasitc shaft that goes from the actuator to the "HVAC Box". This shaft is sheared off flush with the actuator. What is my next course of action? Can the broken piece be removed without tearing the dash apart? Im afraid there must be something blocking the blend door, that made is shear off in the first place. What kind of job is is to get at something like that? Thank you.

Hey all, Hope someone out there can help. Basically the Trucks AC was working fine and then the other day only blowing warm air. Ran the truck on a 20 minute trip with the AC on as I've heard it can take a bit to come on and still nothing but warm air. Check the refrigerant and it was fine. When turning on the AC you can hear/feel the power transfer as the motor send power. Took a look at the compressor and it was not turning when the AC was switched on. Got my hand down there and was able to move it so I know it's not seized up. Checked fuses in the cabin and under the hood that were related to the AC and all were good. Anybody have any idea what could be causing this? I'd like to fix it myself as I enjoy that sort of thing also would like to avid dealer pricing where ever possible. Thanks in advance....

| Low refrigerate is never the root cause of a cooling problem, just a symptom of a another problem somewhere else in the system.Chevy P/U's are notorious for actuator blend door problems which can affect the ability to control the air or heat depending on where it got stuck or quit working.. | |
