HVAC/AC issue

[4183jose]

My 2007 yukon denali started acting up with the rear shutting off and the front max ac going off too, I was ready to tear into everything and found out about a calibration procedure. I did the calibration and that was all I had to do. I recommend doing this first before replacing anything, as it costs nothing.

The tahoes or yukons have three small fuses you must pull. just look for hvac front and rear aux.
