SOURCE: Rear A/C not working on my 2000 GMC Safari

I think that there is 2 solutions:

1. Check if there is enough gas.

2. Maybe you have to change the gas, maybe you put gas that don't fix to your car.

SOURCE: 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...

SOURCE: Front AC Blower quit working. Rear AC blower

The first thing I would do is check to see if a fuse is blown or bad relay. Then I would unplug the blower motor with a test light make sure you are getting power to the blower located on the far passenger side of the vehicle under the dash if it has power and good ground then suspect vaulty motor. If you are not getting power at the plug then you might have a bad switch or resister. If it does have a blown fuse remember they usually blow for a reason like faulty wiring or even a in the motor itself. I would also recommend that you change the ac cabin filters behind the glove box if they have not been changed most people neglect them on that vehicle because they are a little more difficult to change, after removing the glove box there is a metal bracket in the way of opening the cabin filter compartment. They wont cause a blower motor to not work, however they do restrict airflow to the evaporator and they protect you from pollen, dust, and even exhaust gases. Hope this helps.

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

My 1998 GMC Safari ac works well (cold) in the rear. The front AC is just barely cool. Ac reads a good charge, not over or under charged. What could cause this?


The blend door is not fully closed for the front. GM's are bad for that. Also check the vaccuum line for the door.
