j-body.org forums: HVAC Blower only works in two highest speeds – Our 97 Cavalier has developed this issue. Apparently it’s a fairly common problem in J-Body cars, and my brother-in-law’s Grand Prix has the same problem. There’s a resistor pack under the dash that limits the current flowing to the fan for low and medium speeds. Apparently, it sucks and burns out all the time. I’m assuming that ours is factory so that means it’s lasted six years. Anyways, link goes to forum discussion of this part. What a stupid design…
