86 4000Q window likes to go down, not up

     Hi all,
     
     The driver power window in my car likes to go down, but it doesn't 
     like to go up immediately.  When I pull through a toll booth, and go 
     to raise it, I have to hold my finger on the button for a few seconds, 
     which seems like an eternity.  Then all of a sudden, it goes up.  When 
     it's in that mood, it will always go further down if I take my finger 
     off the switch in mid position.  It really scares me; I'm just waiting 
     for the day it decided it will not go up at all.  I replaced the door 
     due to an accident a while ago, and I got a new (used) window motor 
     with that door.  It behaves the same way before and after the door 
     replacement, so I think the problem is somewhere else.  I was thinking 
     of taking the switch apart to clean the contacts.  Any thoughts?
     
     Thanks in advance....
