The switch has 4 level settings. I can only hear the fan roar at 3 and 4 (4 is max). Is there a relay or resistor that control 1st and 2nd speed on this vehicle?

The speed should be controlled by a resistor module.

Thanks, I have just replaced mine. It locates next to the blower motor under the dash on passenger side. It is a ceramic thick film resistor plate. I can see several burnt marked at few places what looks like water stain or condensation residue. I would rather see the old resistor coils type than this ceramic plate which seems to be not as reliable. Anyway, I hope it is good for few more years.

Second question about this since reading today (other car was a Grand Prix..I think). Here was my response to that guy:
I have the same problem on my Grand Am, 2000. The fan only works on 3,4, and 5. I have had a water leak that got into the fuse boxes causing rust and corrosion. This has knocked out a few electrical things: Keyless remote, lock button on the doors (the unlock part still works though), had to pull the fuse for the fog lamps as they would come on in a rain storm. Same thing for the trunk, found it open after it rained. Now I have two zip lock freezer bags around the fuse housing units. It actually blocks the water from hitting the fuses and causes it to go directly onto the floor mat/side of car near hood release. You really want to check this out. Pontiacs are notorious for leaking water.
