    I have a '02 yukon xl that has an air conditioner that is blowing hot air, I tried to recharge it and the refrigerant pressure was high (65psi with air conditioner on). Has anyone else had this problem? Could it be a stuck expansion valve?

    Is it blowing hot air out of both the driver side & passenger side?

    i heard of someone else having this problem, it could be the temp control module itself

    Don't know what my pressure was, but my 04 sub did the same thing. Ended up being the damper door? getting stuck in the hot air position. Just kept running the switch between hot and cold, heard it finally close, and all has been good since.
