Re: a/c problem

Maybe the rear air box is hung in the heat position. [there are two air boxes for dual air rigs ] On the Tahoe it will be on the rear right hand side there is even an access panel if I remember, but to get total access you will have to remove the hole panel back there. Sometimes a good whack on it can help it along and dislodge whatever is stopping the door from free movement. It is quite common. Jim
