Strange A/C issue

[cup0joe]

Hi All,
I have a 99 tahoe lt with front and rear air. Front air is warmish, Rear air is freezing cold. What do you think? Some kind of air flow door? Anyone have the same problem before? if so do you think you could snap a pic of the problem location?
thanks

I could be mistaken, but I believe that is 2 separate units. You may just need a recharge under the hood.

Yep, the second unit is in the rear, its behind the plastic grill on the right side of the cargo area. I had the same problem, recharged it the one under the hood, and its good
