Question about 2007 Chevrolet Tahoe
Just the a/c ? Check to see if you can get heat from the front. If the fan is not blowing check to see if you have power to the cabin fan. This can be tested with a digital multimeter let me know what you find.

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..

Notorious for plugged heater cores. Also updated plastic restriction couplers mounted at heater core available from dealer. Try back flushing heater core. Run engine till its at operating temperature then carefully hold the inlet and outlet hose breifly with heater fan on high if hoses are nearly the same temp then flow is good , if not then core is plugged.

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?
