Open the acces-panel (20 Screws)
"Click" over the catch on the tailgate on the drivers side.
place garden-furniture to suport window as you roll it open.
You can disconnect the cable at the motor and run it up with a Power-drill instead.(lots of fun).
With the window out of the way you can remove the regulator-assembly 3-4 bolts and the hole thing can be taken out with ease.
Now first you can get to the key-switch assembly. 2 quick nuts, jiggle and its out. Inspect, clean and order new parts.
When you get the switch out.Basically there is a "U" shaped contact with a cam in the middle .The cam is turned by the key.When turned the cam causes the "U" shaped contact to touch the outer contact and the window moves. On mine the contacts on both sides of the "U" were burnt. So I cleaned them off best I could and took the brass bottom part to an old bulb and a set of sidecuts and made 2 pieces just a wide as the contact and long enough to bend in half and go over it. I then soldered it in place where the old contacts were and it works like a charm.Seemed more fun then to but a new one for $50.00.
