Question about 1998 GMC Suburban
Had the ac checked at a shade tree mechanic he showed me that there was enough freon in it and had a hard time explaining why this problem existed, as i stated it blows ice cold in the rear and luke warm up front i spoke to a regular ac mechanic and he seemed to think that there was a actuater valve somewhere under the dash that controls the door on the heater core and that valve is vacumn actuated and the that there is a vacumn leak somewhere or the valve has gone bad. if this is the problem how much for the part, and is it feasible for me to do it or pay this guy to do it
I have the exact same issue did you ever solve it?

No its a bit difficult,another problem could be venturi/restrictor in the entrance to the interior rad for the AC ,if the back one is working then so should the front one ,your man is right it could be a trampilla ,sorry forgot the word in english ,been living in spain too long but this is the vacumn operated valve ,could have a split vac pipe as well that operates the trampilla
