HVAC Fan Speed Problem

[91GranSport]

I have four settings on my HVAC Fan Speed controls:

 

Low

Medium

High

Max

 

At the moment, only Max works. It blows air at the rate it should. However, the other three settings don't blow air as fast as they normally would. High blows air slower than Low when it was working normally, and Medium and Low barely work. What can be the problem? Thanks.

My dad had the same prob on his 85 regal. It turned out to be just the fan switch itelf. You can test the switch with a continuity tester to make sure. If you don't know how to do this send me a pm.

Thanks for the heads up, I'm going to try to take this shit apart today or tomorrow if I have the chance. I'll email you with the results and hopefully we can find a solution.
