2002 GMC Yukon front A/C blowing warm air

Here is a TSB (Technical Service Bulletin) for your vehicle for loss of temp control.
File In Section: 01 - HVAC
Bulletin No.: 01-01-39-007
Loss Of HVAC System Mode and/or Temperature Control 

(Reroute Wiring Harness)
1999-2002 Chevrolet and GMC C/K Pickup Models (Silverado and Sierra) 1999-2002 Chevrolet and GMC C/K Utility Models (Avalanche, Suburban, Tahoe, Yukon, Yukon XL, Denali) 2001 GMC Sierra C3

Some customers may comment that they cannot control the HVAC system modes and/or the temperature. These concerns may be intermittent.
There may be poor terminal contact and/or bent terminals in connectors C206 (RPO C68 automatic HVAC controls) or C296 (RPO C60 manual HVAC controls). Excessive tension on the wires due to the wiring harness being miss routed in the instrument panel carrier may cause these conditions.

If the warranty campaign is over i am sure they can or may have in the system on how to correct the problem.
Good luck and hope this helps, keep me posted if you need help on to the repair procedure.

Ac blowing hot air

This sounds like the mode selector is stuck on heat. Under the dash is the location of the hvac plenum and you need to check the cables and levers that are on it to see if they move when heat and cold are changed as well as the lever for where the air is directed.
