Hello all,

New here and love my Tahoe. I've been researching the forum and have will use some of the advice given on some of the threads about possible fixes for my A/C problem. Maybe I can save some time and money if someone with knowledge can maybe pinpoint the issue:

No matter if the A/C button is pushed or not, and the temp sliders are set at hot or cold, air only blows through the defrost vents at hot temperature. And the rear air doesn't work at all. Was wondering if anyone can help pin point the issue as to why do the air vents not work and only hot air blows through the defrost vents? I'm not too vehicle saavy, but love to learn, so anyone that can guide me as to where the A/C components are in the engine and blowers for both the front and rear vents would be greatly appreciated!!
