I have a 2006 GMC Sierra 1500 4x4. A/c has been out for over 2 years had a bad compressor never got around to fixing it. Today I replaced the compressor, condenser, accumulator, orifice tube, and flushed all lines. Took it up to my buddy at the dealership and we charged it up. Put it under vacuum for a bit and no leaks. Drove home about 12 miles no problems blew ice cold. Left to go to the store about 2 hours later started it up the ac button was on but clutch wasn’t engaged and ac blowing warm. Turned the button off then back on clutch engaged and blew ice cold. About 10-15 seconds clutch disengages blows hot cycle the button again blows cold again. Every 10 seconds or so it blows hot and I have to cycle the ac button on the dash again get cold air. I know the compressor clutch should cycle on and off that’s normal but I don’t think it should be that frequent and you shouldn’t feel that significant of a temperature change right? And when it cycles off it doesn’t come back on unless you cycle the button. I’m thinking a issue with the low pressure switch on the accumulator but any advice?
My 2007 Denali was recently in an accident with pont of inpact at the driver rear tire near the compressor, shock, and leveling sensor. Prior to this I have replaced my rear shocks and compressor with Arnott factory replacement components and all have been working well and with no error codes. I have noticed that the compressor to level the rear suspension is not turning on at startup every time. However, I am not getting any error code. To start I want to confirm my memory servers me correct. Is the autoleveling compressor supposed to activate at startup every time?
I purchased a 2007 Yukon XL Denali about 2 months ago (107,000 miles). The air ride suspension worked fine when I purchase the vehicle. It was a bit loud but worked great. I had noticed for the past week that the compressor has not activated. I put a load on the truck and it still did not activate. I am not getting any error codes on the dash board. Any ideas that I can try before I purchase a new compressor?
