Good evening all!
This is my first post, so I hope I am using it correctly.
I own a 2006 Grand Prix and discovered a few days back that my blower motor for the heat (I live in Michigan) started making a slight grinding/murmuring sound when turned on. The sound was constant from low to high, if you will. Yesterday when I turned the heat on the blower motor did not work at all. I tried low to high on both heat and AC and nothing. However, I did notice that when I was driving i got slight heat from the vents. When parked or idling I got nothing. Today, I drove about 50mph and was able to get more heat from the vents. I guess the higher the speed the more heat.
What are the opinions out there about my issue? Blower motor? Blower motor resistor? ??????
Thanks in advance.
