Question about 2001 Oldsmobile Alero
Iv checked all the fuses and they are fine
I had a similar problem - except only High worked on mine. When we got the snow on Friday, mine stopped working altogether!
Well, the solution on mine, which I found somewhere online, was that it was the resistor. It was $25 at Pep Boys and it is replaced by taking out the glove box and dashboard foot thing (all by screws) and it unscrews by two screws and unplugs.
I found this detailed description for another type of car - but it is the same exact procedure (my brother replaced it on Sunday).
"To get access to the heater resistor you will have to take the passenger side glovebox liner out by unscrewing the screws holding it in place.You should see where 2 or 3 wiring connectors are secured.Look above and behind these connectors and you will wiring connector that appears to plug directly into the air circulation housing,but actually that is the resistor screwed into the housing.Disconnect the wiring connector and the2 screws holding it into place and it will pull right out.There is not a lot of room to work back there so you may have a little trouble getting to that right side screw.Good luck "

It is common for the blower motor and the speed resistor module to fail on Alero's, Malibu's and Grand Am's. Water leaks through the cowling by the windshield wipers and finds it's way inside the blower housing and damages the blower and resistor module. There is a GM service bulletin that describes the fix. Bulletin #01-08-57-003. It basically is a foam strip that deflects and seals the point of entry for the water.
