odd HVAC problem
As I move the blower control more air comes out with each click but when I get to high, nothing comes out. There are no noises and I don't hear the air blowing at all. I guess the blower is shot? Ideas?

Re: odd HVAC problem
my fan did the same thing. i replaced the hvac control and... nothing. then i read the wiring diagram and found the culprit. the high fan relay located under the hood mounted on a small bracket right in front of the blower motor. i have a pic but no idea how to get the image into this post.
