Hey guys!,

My a/c is blowing ice cold in the front but in rear its blowing warm. Seems like every once in a while it will blow cool but not cold like front. I have heard there is a valve of some sort in the rear which opens and closes. All the lines underneath look ok and dont see anything leaking. Any info on what I can do would be appreciated so i dont have to bring to dealer!

 

Since you said the rear is blowing this may not apply. The intake is by the cargo door, passenger side. Is it blocked?

 

Could be the rear evaporator is icing up.

 

If there is a blend door involved it could be hanging open and mixing the hot and cold air....

 

yea my buddy who is a chevy mech thinks its the blend door. not a cheap part $188 and that's cost. Hopefully that fixes it. Will try it.
