Ac Blowing Hot Air From Front Vents On 2004 Gmc Yukon Xl

[matus5317]

I have a 2004 GMC Yukon XL blowing hot air from DS and PS front vents. The rear ac blows cold air. I have a dual auto climate control unit. I have relpaced the blend door on the PS. I have re-calibarted the unit pullin the HVAC fuse. I have check the Hi/Low pressure on the ac compressor and check ok. What do i need to check to correct the problem with the front vents blowing hot air?

not sure if you have seen any other posts about your prob with other gm owners, but it sounds like you have a compressor problem.
