Side View Mirror Not responding...

Drivers Side View Mirror Not responding to the switch, although the passengers side is (moves without any problems)! Cold there be a motor inside the mirror that has blown? or is the switch defective?

Thanks for your help

if the passenger mirror moves in all directions then the motor in the drivers mirror or the part of the switch that selects the mirror could be bad. check for any lose connections first. do you hear any noise comming from the drivers mirror at all?
