Question about 2000 GMC Yukon XL
Did you check the fuses under the hood? Do that if not. Also in some models the controls for the climate system are routed through the radio. Contact this company and ask them about the possibility that you have that kind of problem from the aftermarket radio you put in. www.crutchfield.com

SOURCE: Dash vents will not blow air
It may be the mode actuator. Have you heard any clicking or other strange noise ? Under the drivers rear seat, in a plastic box is a fuse panel. Remove the two retainers, and the cover. Remove the HVAC or A/C fuse for a minute or two. Reinstall the fuse and this will make the A/C system relearn. Whwn you put the fuses back do not touch the A/C controls. Start the truck and leave it run for two or three minutes. Then try to change the vent from floor to vent and defrost. If this does not work you will need a mode motor. Good Luck

Is it a new vehicle? I had a new vehicle that had the same problem. Answer was that the holes weren't punched out of the vent.
