2001 Chev Suburban Rear AC fan/blower not working

I recently replaced the rear blower motor on my 2001 Chev Suburban because it was not working. This was not the problem as the unit still does not work. I have checked all the fuses and we do have power to the relay mounted just before the blower itself. I was wondering if there was a way to test the relay in order to isolate the problem. Please help, it's hot in Central Illinois in July.

SOURCE: where is the blower motor resistor on a 1999 chev

It is behind your glove box. You have to make sure when take out the glove box be careful of the tabs and also remove the wire on the side. You will see a black box with a a bunch of wires coming out of it. You need to disconnect that mess of wires and remove the two screws that are holding the resistor in the box. Remove it and put the new one in. Be care not to bend the coils all up on the resister. Hope this makes sense, keep me posted, be glad to help.

SOURCE: ac doesnt work

Check the grounding of the blower motor it's self. Gm had a small issue with the blower motor loosing it's ground. Run a test ground wire from the battery to the blower motor. If this doesn't help, replace motor.

SOURCE: rear blower not working from overhead or rear

I believe that your vehicle has two large fuse/relay assemblies. One is under the hood and the other"may" be under the drivers side passenger seat. The owners manual will list all, and I mean many" fuses and relays. Check them all with a test light or if you think a relay is at fault just switch to alike relays and see if that fixes your problem.

Suburban rear blower

No, it is more likely a bad blower resister. That's located in the housing, next to the blower motor so you will have to remove the trim to uncover the unit.

Rear blower

If it does not work on any speed then I would expect a bad blower motor. With the key on and the blower speed set to high try tapping on it. If it starts to work it needs to be replaced. If it still will not work than you will need to see if there is power and ground at the blower motor.

Rear AC fan will not run in lo med or hi, switch or is there resistors on the fan that need checked?

When a blower motor does not turn on in low or med. and only turns on high its usally a resistor block. If nothing works it is most likely the bolwer motor itself or a fuse.

My rear AC blower dosent work. I dont seem to


Thanks for using Fixya!

check the wire terminals from the fan motor, its possible that they are loose. Also check the relays if they are good. Just swap out the other relays to test if it will work. These relays can be found in the fuse box under the dash or under the hood.

Have a great day.
