91GranSport Posted August 21, 2003 Report Share Posted August 21, 2003 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. Quote Link to comment Share on other sites More sharing options...
91cutty Posted August 21, 2003 Report Share Posted August 21, 2003 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. Quote Link to comment Share on other sites More sharing options...

I'll email you with the results and hopefully we can find a solution. My dad had the same prob on his 85 regal. It turned out to be just the fan switch itelf.
