I have a 2002 that I’m having a/c problems and can’t figure it out. When you turn the ac on it starts to work and blow cold air but 6-10 sec later it kicks off and the ac light flashes. I have done the self test and it steady flashes with no codes. I have Techstream and have looked all over it and can’t find anywhere to get ac codes on it. I had my mechanic check it out and he confirmed that the relay is good, the charge is correct and the compressor engages and works correctly. I’m guessing it a switch but not sure where to start. I’m new to these cars and learning so any and all information is appreciated!!
