Desperate for help! Long-time lurker...
I have a '15 Sierra 5.3L with some A/C problems and I can't take the heat! Last summer it wouldn't hold any refrigerant and I didn't fix it right away because I would be gone overseas for 9 months. When I got back, I replaced the infamous condenser that displayed huge amounts of leakage in the same upper right corner. Pulled a vacuum, charged it, PAG oil, etc... it worked perfectly for about 5 months. NOW.... out of nowhere, it's blowing hot air again. I hooked up gauges and initially before doing anything else it showed 100PSI on the low and 150PSI on the high with the compressor refusing to engage. I've replaced the pressure sensor hoping for a cheap fix to no success. Pulled a vacuum (vacuum held for 15 minutes) and attempted to refill, but the compressor refuses to engage. Upon starting the engine the clutch face looks like it is engaging and stops after a few seconds. With the A/C on, the clutch face IS magnetized and seems like it is attempting to engage spinning slowly and making half turns every so often. It doesn't make any weird noises and is free spinning while "engaged". I have read about trying to jump the clutch coil directly with battery power to see if it engages, but I don't know if there is an easier way (i.e. relay) than reaching down to the harness on the compressor.
Do I need a new compressor? Or a new clutch? Or can someone smarter than me tell me what I'm doing wrong haha
Hello everyone. I'm new to the forum. But I came here because I know I can get good info from this site. So let's get to it. I have a 1990 Chevy C1500. It didn't come with A/C. It's getting hot out. I know it's possible to add A/C. I just don't know where to start. I also know that there are under dash units that will not fit my truck. I also know that auto A/C shops can get kits for specific vehicles, however I can't find one for my exact year, make, and model anywhere. Would anyone be able to put me in the right direction for one of these kits or help me with my problem? Thanks so much, everyone.
The a/c on/off and blower position display on the mylink screen started rapidly flashing on and off. The air won’t turn on, it just acts as though it’s turning off and on very fast but on screen only. What would cause this? Any ideas what it might be? Thanks. (See video)
My 2004 Silverado 1500 AC is not blowing out of the top vents, it only blows from bottom. I took it to get diagnosed and asked for name and part number but when I looked online I couldn't find it. He said he it was called a "control head' part number 599-009. What can I do to fix this?
Not sure if I'm posting this in the right thread but mabey y'all can help me. I recently bought a 08' Silverado from a guy that had it since he bought it brand new and the last two years he had it he had to press the recerculate button to get cold air because the fresh air came out warm , any ideas?
