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.
