Best Answer

I have a 2000 Grand Prix with the same problem. I found this response on another website:

"The problem is the blower motor resistor. This is a very common problem. It is located under the passenger side of the dash in front of the blower motor. The replacement part should be an updated and improved design."

Now I just have to figure out how hard to get at this is gonna be.

Good Luck.

I had the exact problem w/ one of my own. It is the resistor board. It is common on GM vehicles newer. They redeigned this particular part due to failure history. It is simple to change;also. It is located on the righthand side of the vehicle inside the cabin. Look down in the corner near the firewall and you will see a cvr that needs to be removed. After removing that cvr you will see a harness with a plug on it. That's it. Remove the two screws and wala the resistor bank appears. Reverse these steps to complete. HAVE A GOOD TIME!!!

The fact that you are having blower motor AND headlight problems points to ignition switch failure. Power to both systems comes from the ignition switch and this is a common Grand Prix problem. Here's the fix:

2000 grand am sometimes heater blower works sometimes not - any answers?

If a 2000 Grand Am sometimes has the heater blower working and sometimes it won't, the problem could be with the heater relay switch. The heater relay switch lets the heater blower know when to come on and when to go off. In most vehicles this switch is behind the glove compartment. This part sometimes gets corroded from condensation in this area.
