Fan only works on highest and one below

I have an Alero, which is a pretty cheap car, and I now have a problem with the interior fan for heating and a/c.

Seems as though the blower will only work on the 4th and 5th position, but not on the 1st, 2nd, or 3rd?

I thought at first a fuse, checked out under the hood. What the heck are those big square fuses, anyhow? They are like 3/4" square around maybe?

But, logic dictates that the blower fan is on one fuse, not more than one.

The car is still under warranty, but why pay $50 if it is something I can fix for under that?

Oh, and the Goodyears that came with it barely lasted 30k miles. Ef the blimp.

TIA

The resistor card controlling your fan speed is gone. Not sure where you are but I just replaced the one in my Grand Am 2 weeks ago for ~$26 Can. and about 3/4 hr of my time.

It does, it does. Lower 48, but that doesn't make any difference.

Quick google suggests you're right, of course. Sounds as though this is not a Pep Boys/AutoZone type part. More of a NAPA part. Could be wrong.

And, 45 minutes of my time is free. 45 minutes of a mechanics time is likely past any deductible from GM.

I will search for the part next daylight. But, my concern is I go and make something worse by trying to fix it myself.

Thanks again friendly Internet user.

As another person who has an Alero (in my case a 2003), that also has the three lower fan settings not working, I agree that it probably is the resistor.

The repair manual doesn't seem to think it is a really tough job, but one thing it does do is remind you to disconnect the airbag sensors to do the job.

This seems to be another one of those "GM-ism's" that, on the face of things are not as serious as an engine or transmission, but sure get annoying.

Replacing both of the front wheel bearing / hub assemblies has been another annoyance.

Hope this helps.
