Hi,

2001 Silverado 4x4. The fan motor doesn't run on setting 2. 1,3,4,5 all work fine. Any ideas?

Thanks to all for all the posts here. Very helpful.

Under the dash on the right side you will find the blower moter. Near the motor there is a small circit board wth 3 or 4 wires plugged in to it. It is the resistor for the blower motor and is faulty. The same thing happened to my 2000. The parts counter guy at the dealer said it is a very common problem.

TRAILDOG,
can you change just the resistor on a 2000 or is it integrated with the blower motor, if it can be changed do you know the part number and price offhand?

It is not part of the blower motor but is mounted near it. I dont remember the part number. When I changed mine I got the number off of the old one. It cost about $20.00.

Thanks Traildog, Guess i'll start looking, my 1 & 2 speeds are dead, the rest work fine.
I live in Hawaii so i can add another 10-15 bucks to that price!!!

Try gmpartsdirect.com You might even be able to look up a part number on ther site.

Traildog,

checked the web site, ordered the part , 20 bucks and some change, including shipping, and believe me they really stick it to us on shipping charges but alot of times its cheaper then the fealer prices.

thanks alot for the help...............

fealer prices?????????????? OOPS..........DEALER prices

I am getting tired of having the AC either off or blasting.

I work for GM and am disappointed that these common problems are ignored except to fix them for the next model year. Maybe.

fealer prices may be correct because when i go to the dealer i come away feeling molested....JJ

Now that you mention it...................I wondered wat that feeling was........just couldnt quite describe it !!!!!!!!!!!!!

Traildog,
Got it changed, you forgot to mention what a son of a gun it was to get the rear screw off of the blower motor cover to get to the electrical connector, after a little sweat and a couple bad words, I got it.

If anyone is interested the part number is 15305077

Thanks again
