Is both switches faulty? If so it could be the teeth on the ratchet worn Here's a switch how-to on this page http://st162.net/forums/viewtopic.php?f=57&t=3828&p=62441#p62441
Good tip there Sean, didn't know that as I've only had pass side failure sofar Looks like he needs to check both switches?
check your drivers first, it gets the most abuse... then check the passenger, the drivers one will work the passenger one even if the passengers one is gone i think.... :?: so worst case scenario , you will be able to get both windows working up and down. Check with a continuity tester before you split the switch
