Master Power Window Switch

Testing of the master window regulator control switch should be performed with the master window regulator control switch removed from the vehicle. Use a self-powered test lamp or an ohmmeter such as Rotunda 73 Digital Multimeter 105-R0051 or equivalent.
1. Clip one test lead probe on Pin 6 (ground).
2. With both toggle switches in the neutral position, Pins 1, 2, 3 and 4 should have continuity to Pin 6.
3. Push both toggle switches to raise both windows. Both Pins 1 and 3 should have no continuity to Pin 6.
4. Push both toggle switches to lower both windows. Both Pins 2 and 4 should have no continuity to Pin 6.
5. Remove the test lead from Pin 6 and connect to Pin 5 (hot feed pin). With both toggle switches in the neutral position, Pin 5 should have continuity only with itself.
6. Push both toggle switches to raise both windows. Both Pins 1 and 3 should have continuity to Pin 5.
7. Push both toggle switches to lower both windows. Both Pins 2 and 4 should have continuity to Pin 5.
8. If any one toggle switch does not test as stated, replace the complete master window regulator control switch.
