Question about 2005 GMC Yukon
The vehicle has a two-zone heating/air system. With the a/c on, the rear vents are producing cool air while the front vents produce only heat.
What is the solution to this problem? Thanks.
In the middle of the passenger side just under the dash on the heater there is a motor that adjust the air flow. Take it out and manually open the flap. Both sides get the same temperature but I can drive mine in the winter now.

I have an 04 yukon, same issue, the quick fix someone else spoke about does work, but for how long, i dont know, quick fix: remove 40 watt green box looking fuse from under the hood for at least 10 minutes, check owners manual, should say blower, i also took out the heater/ac and hvac fuses from the side dash fuse box, mine were 30 and 10 watt, after 10 minutes, i replaced these fues and for now my ac has been working fine, but now i cant get the heater to work on the driver side, but honestly, i live in louisiana, so no heat is not an issue for me,

Hey folks, my understanding is there is a 'technical bulletin' for erractic AC vent behavior for 2004-2005 Yukons. This is not necessarily a warranty repair, so ask your dealer for further details.
