Pinout for '87-96 Dash Switch CONNECTOR (harness side) for Tailgate Window
(Looking into the switch, the pins would be reversed.)
Pin 2 is normally closed to pin 4, & pin 3 to pin 5. When the switch is operated, either pin 3 or pin 4 is momentarily opened from ground & closed to pin 1 (power).
To bypass the dash switch & test the rest of the circuit for DOWN, turn the key to RUN or ACC, install a jumper (paperclip, etc.) from 3 (P/LG) to either ground (2 or 5 Bk), then install a jumper from 1 to 4. To test UP, jumper 4 to either ground, and 3 to 1. If the motor doesn't spin during both tests, the dash switch is NOT the only fault.
Maximum current draw when glass is moving is 4A @ 14VDC.
