Can you raise the window in my 1998 Pontiac transport van?

Answer 1

Yes, I can. Remove the plastic housing from the door with a screwdriver - it pops off/out. release the button/control housing allowing you to clearly see and work with the wiring harness. The button itself easily is removed from the harness connector [well it's not physically easy - you have to pull and rock it and watch the clasps meant to keep it in place.

When you have fully removed the 'button' you will have a connector with 7 wires - a clip - w 7 connecting points for the switch to slide in. Both ends are ground but connect a small piece of wire to Terminal 1 or the small black wire. Jump or connect the other end to terminal 3 [assuming skinny black wire on end is 1] Now with 1 + 3 connected or shorted - also connect with a separate jumber to terminals 3 + 4 - remember there are seven looking like this _ _ _ _ _ _ _. Short 1 and 3 and then short 3 to 4 giving power to motor with voltage polarity set for 'up'. IT's that simple. For Down - short same 1 +3 and then 4 + 5 as 'switch' giving power to lower window. Good Luck.
