Generally, if everything dims, that indicates a short of some kind. It is possible that the blower motor is going out or one of the windings has shorted to another. Also, it could be that the alternator is going and can't keep up with the load. The blower motor is a pretty high current item. I'd start with the alternator as it is about the easiest to get to. Pull it and take it to a parts house and get them to test it. Same with the regulator.
