I know this has been discussed here before, my mechanic cannot seem to figure out the issue. He has check all lines for leaks, thermostat replaced. The dealership refuses to look at it because the thermostat was not replaced by them, they clear the code, 3-4 hours later it comes back on... I don't know where else to turn for some advice for what might be causing this code to come up. Any ideas would be greatly appreciated!
I honestly don't know the code, This message comes up in the info center then it shuts off the air conditioner and kicks the front fan on max. When my weekend comes I'm going to head back to the dealer and ask what code is coming up exactly.
I'm on a couple different forums myself. Thermostats on each forum are well documented, regardless of the vehicle, of being "bad" right out of the box. "Bad" can mean a lot of things - but typically they open (or don't open) at temps different than their rating. So based just on what I've read here already, you have a couple very simple options - put in a stock-rated TStat, put in another new 160° TStat, and/or get a tuner to turn off that code.
I ordered a Mr Gasket 6367 from summit racing, I got that part number from Jamies post on this forum. Maybe I'll order another or just get another GM 180° to replace this one.
It's been mid to high 100's here and driving with no ac is not the most comfortable thing to do!
