The problem will usually be because the air diverter door actuator on the HVAC box under the dash has failed, is stuck or is not getting the required signal from your HVAC control system.
SOURCE: no air flow to dash vents and feet vents
99% of the time when they do that it is the control head. that is the thing you adjust all your temp settings on. have to purchase from dealer. have last eight digits of vin # when ordering.
SOURCE: 2005 tahoe no air blowing
as long as all the fuses are good.. its probably the blower resistor/module... located next to the blower motor under the pass. side of the dash..
SOURCE: raer a/c works but front blows hot air on my 99 tahoe
My 04 tahoe had to have the a/c door actuator replaced as well, same problem. 100.00 part from dealer if you want to do it yourself.
SOURCE: 2001 tahoe front heater not working, rear heater blows warm air
I have the same problem with my 2001 Tahoe. The front blower is working, its blowing strong, but its cold air even with the temp setting as high as it can get. The rear blows hot air. The engine temp guage is at about 210ish which is close to being normal (220). I just replaced the thermostate a few months ago, I don't know if its bad again, or it I deluted the antifreeze too much and it frooze the heater core, or if the heater core just went bad. Any one know what the cause could be?
