It could be your fuse or relay or blower motor resistor

AC blower stopped working on my 2004 GMC EnvoyXL. The rear AC blower works but not the front. Checked the fuses and relays, they appear to be OK.


does it work on heat mode if not then it is probably the blower motor switch in the dash or the blower itself

Rear heat or rear air conditoner not workin in my 1997 gmc safari


two different problems !

Rear heater problem: find under the hood where is hose for cooling liquid goes to front heating core!
you will see there also vacuum tubesgoing in to little valve ! disconnect the vaccum tubes ( engine off)
and spray in wd 40 in to the vlave ... valve is stuck and wont open flow to rear heater !

you do not have to replace tha thing . its very well made and because you dont turn this often in summer
it gets stuck. i had same problem. also make sure vacuum is working - Engine running turn rear heater on - vacuum sucks to open valve. and before that make sure fuse is ok .

for rear AC mine does not work either and it is leak on pipes that go from front to rear .. 10 feet of pipes and tubing $$ expensive repair ... forget it ... open the window...
