You know, just from reading articles a couple of years ago on the forum I was pretty sure I read somewhere the blower motor resistor is usually what goes bad on our systems.
I took the blower motor out to clean it about a year ago - a/c was making weird noises and turned out the blower motor was full of leafs. I remember exactly where to resistor is located at and what it looks like. Thanks for your heads up. I'll go ahead and order a new resistor right away. Thanks again!
