Hey Thanx fordman351,
Who knows who spilt what in it before I got it, I was thinking of getting a new Assy for that reason and all the U and D's have just about rubbed off.
But now I'll give 'em a good clean and at the same time see if I can't fix up the missing U and D's.. Any Ideas on that?

When ya pull the whole switch board out take the rocker (the actual switch itself) out and give it a good clean underneath and put a dab of electrical grease on metal contacts and on the black spring loaded lugs on the rocker. Also make sure you give the arm that is in contact with the auto down solenoid a good clean, as anything on this arm will make the drivers window switch stick in the down position.

As for the 'U' and 'D' letters wearing off maybe get a metal stamp and stamp the letters in the buttons or get them engraved proffessionally. You would have to use the windows a bloody lot before those letters wore out lol!
