About a week ago my blower in the low setting started making a tweeting sound and eventually petered out either blowing very low or not at all. The blower in the high position blew fine, cold till a few days ago.
I am driving up the road, in a suit no less, and all of sudden I hear a grunt sound and then dead completely...Nothing not at any speed.
I am confused, I checked fuses under the hood but all is ok..I am at a loss and I hope someone can shed some light on this issue for me
