If equipped, remove the IP sound insulator.

Disconnect the electrical connection from the blower motor.

Remove the blower motor resistor retaining screws.

Thats over by the 02 Cabin Filter right?..  Thanks I will look in the morning..Do the dealers stock this part or should I get it cheaper at Pep boys..?
 
yup, to the right of the filter, GM part # 15305077
 
I can not believe they are still using a design I found in my first Chevy, 1975 K5 Blazer. I went through at least 7 of them over 18 years. I used to go to the junk yard and get them, use it for a year or so and then replace it again.

Simple design, but it is probably placed in the housing that is now in the passenger foot well.

Look for a couple of hex headed nut screws and pull out a funny looking piece with a few spring like thingys (thanks YGGM). You'll find one or more burnt off or very discolored ones.

I think I may have attempted to re-solder them once ot twice, but it never worked out. Junk yards were much cheaper than OEM from GM and no one back then, through '92 anyway, ever had the part.

I've been doing a lot of re-soldering tonight!

I just saw the posting with the rest of the nomenclature. I forgot to add there will be a wire loom clip going into it also. That's the stuff!
 
I paid $19.20 for mine from the dealer and they had it in stock.

Part # 89018596 Resistor 9.216  ( I have an 03 )

GMPartsDirect.com was down last night, now it is up and the PN I gave you does not come up. The PN ron posted came up, just be sure it will work on a 02.

For 2002 the GM part number is 89018597(thanks wildfire), You do not have to take the dash apart, it is under the glove box just remove the screws in the middle and on the right JUST loosen the one on the left, then just let the cover rest on the floor, replys #16 - 17 have good pics of what you will see.
