Hey, I have a 2002 Tahoe, My rear AC vents dont blow air at all. It doesnt matter if the front controls are on or the rear, I was thinking it may be the relay that needs to be replaced.

My question is...How do I get to the rear blower motor and relay and resistor?

Is the dis-assembly hard? Does anyone have a right up on how to get to the above mentioned items?

I have done many searches and cant find any info on how to do this.

Thanks in advance for your time and help.

P.S. The front vents and AC work great. This is why I am thinking the relay or resistor went out on the rear.

Have you checked all the under hood fuses and relays, maybe walk a few of the similar ones to see if anything changes....

Harbor Freight has inexpensive (read Made in China) VOMs and are easy to use.

I got it fixed, All the panels in the rear were easy to take off. I checked all the connections and everything seemed fine. Went once more up to the front drivers side fuse box and pulled all the AC fuses and replaced them. It ended up being the 25 fuse that was burnt out. It was not blown...just burnt. Anyways, thanks everyone for all the help. I was glad it was just a burnt fuse.

P.S. I know that fuses are the first thing to check and I did check them all before I started. For some reason I just got a feeling I needed to replace them seeing how all of them had been in the vehicle for 170,xxx miles. Thanks again.

Thanks for the feedback. Not sure what a "burnt" fuse is tho and if it wasn't blown, how it affected the circuit.
