Ok, so only the high setting worked. At least I still had a good flow. So I found out it was a resistor behind the glovebox that needed replaced. Sounds easy enough. I bought one for like 15 bucks (maybe it was 25) I can't remember. I pulled the dashboard out and attempted to replace it. I could see it but the geniuses at GM must have designed it so only a mechanic can get to it. You have to take 2 screws out. The first one is easy enough, but the 2nd one is a real b*tch. I never did end up getting it. Actually, while I was working on the resistor, another problem reared it's ugly head. My rack and pinion crapped out. It was leaking steering fluid like a seive....but that's another complaint. So when I took it in to have the R&P replaced, I had my mechanic change out the resistor. He's awesome, my alero sucks and so does GM!
