1999 Buick Regal HVAC issues
I have a 1999 Buick Regal that has a strange problem. Sometimes no air will come out any vents, either using the AC or Heat. When I turn on the lets say the ac, you here like its on, but no air. Its the same way for the heat.
1. Does the air conditioner use the blower like the heat does?
I have also noticed the when I use heat only, there blower motor seems to make a funny sound, like a squikey noise.
2. Could I have 2 problems as in the control module and blower, or can the blower cause all these problems?
I really appreciate any help on this issue. Thank you.
