So, I just wanted to pass on my experience with this situation. I read lots of posts on this site and others, all saying when your interior blower doesn't work, or only works on high, then you need to change out the resistor. Most people also suggested that you change the blower at the same time, as often a problem with the blower results in a failure of the resistor, which a new one would then just go out due to the blower still pulling too many amps. Fair enough, all makes sense.
So that's what I did. Changed both. And since it was -15 here for the last 4 days, I didn't want to wait for the "1/2 price" parts from the web, instead I opted for the $205 blower and $65 resistor from the dealership. Not a big deal, 10 minute job to swap them out, the money is fine, I have them in my hands in an hour.
Funny part....... STILL DIDN'T WORK. So the Chevy guy in me says: "hey there HAS to be a fuse...." Well, EVERYONE, including the service guys at the dealership, everyone on here and all other places say..... "There isn't a fuse for the interior blower motor. It's just the resistor. That's the fuse." But I check anyway. Can't find anything. I pull every 20 amp or less fuse out of the interior box and the under the hood box. They are all fine.
I give up, call in the dealership troops, break down and take the car (driving in -15 with no blower mind you, 30 miles to work, then 60 miles from there to the dealer) to the dealer. Tell them my story, they have no ideas, but say they'll dig in the next morning......
Well, here comes the funny part. IT HAS A FRICKEN 40 AMP FUSE FOR THE BLOWER! And yes, it was blown. So dumb. Felt like a ding dong. But, I wanted to share this with everyone in case they run into the same thing.
So the fuse is #40, and was a 40 amp, in the interior fuse box. #40 is the first one in the bottom row of the larger fuses.
Hope someone else in the future finds this helpful. The mechanic still said, and I agree, that I needed to replace the resistor and blower anyway. If it blew a 40 amp fuse, something was wrong. Likely the blower motor went bad, wrecked the resistor, which let it work on high, but then the high pulled too much juice and popped the fuse.
Anyhow, that's my story. Hope everyone enjoys.
