    I recently had a new update from GM installed on my truck and now am receiving an error and it won't read the PCM. Anyone experience this and if so how did you correct it?

    LMM A/C issues

    A/C works fine for 5-8 minutes then starts blowing warm air. If I turn off ignition and open driver door then restart truck it will blow cold again for a little while then warm again. Took it to a mechanic and A/C checked out with no problems and blend doors were working properly, he said it...
