Rick, pull the door panel on the driver's side.  Last time I had this problem
come into the shop, the plug that attaches to the power mirror control
switch, had come un-plugged (time and vibration).  I plugged it back in and
all was well.  I then put some aluminum tape around the two plugs to ensure
that this didn't happen again.  Took 15 mins tops.  I hope this is your
problem.

Thanks,
Ken Wilford
