Default Blower motor fan only working on two speeds
Well I went and started the pontiac today outside temp was a balmy 43. Lol. but I decided to start it anyhow just to see how to would run with the chock hooked up. Let it sit about 5 or so minutes and realized I'm not getting any air out of my dash vents. Well the heat sure does work in that car but the fan only works on two settings the 2 in the middle. I'm i on the right track that it's the blower motor.
