Question about 1993 Pontiac Trans Sport
1991 Pontiac Trans Sport Passinger window goes up but not down w button/switch. I remove switch and can make window go up and down by alternately shorting terminals/wires - up and down. THE Button/Switch TESTS GOOD! Replaced button/switch and get same behavior. Is the problem in Driver side button control somehow? [It houses dual control for both windows]. What wire can I short to insure both up and down power? How can I hotwire the control or wires to insure both up and down power? Is there a simple wiring harness diagram for the windows? I've identified most wires - but a SIMPLE schematic of harness and controls would be very helpful. I have chassis diagram from Haynes but its not very helpful. Thanks!
