HEATING/ AIR CONDITIONING

Please do not post to newsgroups in caps, it appears that you are shouting and many consider it rude. If you look through some of the other posts you will notice the lack of anyone using caps even in the subject line. That said, are you sure it's just not the fact that your blower only works at the high setting? If so then your blower motors resistive speed control needs replacing. It's a small module that is a group of several resistors to allow the blower to operate at various speeds, very common failure.
