Stevebfl, thank you for your help. Actually, after my original post I did some more searching through this site and I came a post from Steve where he mentioned that he was the author of the article on continental imports.

The blower motor and regulator were replaced in Oct 2003. Then, about 2-months ago I replaced the activated charcoal filter and in-cabin filter. When I replaced the filters I became skeptical that my indy never replaced the blower motor. The screws holding it in place were rusted and did not show any signs of being tampered with. That said, I'm thinking possibly the blower motor itself is to blame I've heard that the controllers themselves are known to have issues. However, if the actual values diagnostic is showing the changing voltage to the blower motor, then wouldn't that suggest the blower motor is the problem? Is there some other module that is to blame?

For now I am going to look through Startek info to see what I can find.
