My front blower would do that. Then it got to where it would run intermittantly, then not at all. Replaced the switch, and that took care of the problem. Switch was dying I guess. I didn't do this myself as at the time I didn't know about it, but if you replace that switch you might consider relays to go with it. Let the switch turn on the relay, and the relay supply the power to the blower motor. The switch gets hot from the current draw of the motor, and its a cheap switch in a plastic housing. The relays will allow you to supply power without putting all that load on the sitch itself, thereby extending the life of the switch, probably as long as you own the vehicle.
