A/C does not work when ambient temperature is high
Hey guys, I've seen a lot of other A/C issues on here, but none that really are the same as mine. I have a 2010 SS with about 100k on the clock which definitely means my warranty is out. I've noticed that when I go to run my A/C when the temperature outside is about 85 degrees or higher, it will not turn on and will only blow hot air. This is with both the snowflake and recirc buttons on. If it is sitting in my garage on the same type temperature day, it will run for maybe 30 seconds to 1 minute, then turn off.
I can see that the compressor is turning then disengages the clutch and the pulley stops. I'm just seeing if anyone's had this issue and if so, what did they do to take care of this problem. Any help is appreciated.

I had this problem with an older Camaro and it was low on Freon. I would check that first.

Check your Freon level, The higher the temps, the higher the pressure, and the high side switch will turn the compressor off, if you have to much Freon, for example. If it is low the compressor will turn on and off in short intervals. Possible that your Orifice tube is slightly plugged. You need to see where your pressures are at.

if your freon is ok, then change out the AC compressor clutch relay. location and number are in your manual. I had a 2009 honda odyssey that did the same thing you described and would also cause the relief to lift make a noise like air escaping. changed the relay out and top of the freon and it was back to normal. good luck

Don't get one of those do-it-yourself A/C cans, actually get a shop drain, vacuum test, and recharge your system. Then they can tell you how much freon actually came out vs how much it was supposed to have. Have them use some UV Dye to check for leaks later on, too. If the shop can't do all that and guarantee they're not just using those cheap cans, take it somewhere else that can.

Freon is a registered Dupont refrigerant name.
Calling refrigerant Freon, is a bit like calling all soft drinks Coke. |
