use a carpet blower and let it blow under the dash for a few days. this should have been the first thing done while doing the other repairs. it might need a ECM,BCM and some relays.

2004 gmc yukon xl, rear ac/heat not coming on AT ALL. not blowing or anything. stopped suddenly, and has not come back on. checked all fuses and relays. no problems with the from ac


I will assume the ac is still getting cold, just not blowing.
You wouldn't really know unless you pulled the panel and checked the lines.
Causes include the blower motor, resistor, fuse, or switch.

My 2001 yukon front AC fan only blows on high setting. nothing on the other fan settings.


Replace the blower motor resistor located in the blower housing under the dash on the passenger side and you will be good to go.
