Switch Inputs Test
NOTE:
Control unit only controls driver's door window.
Remove driver's door panel. Unplug connectors from control unit. To test unit, keep driver's switch connector connected with door wire harness. Using a DVOM, perform switch input tests in Fig 1 . If all input test results are okay, inspect connector and terminals for damage and proper fit. If connector is okay and power windows still malfunction, replace control unit.
