Window Switch: Notes

With switch removed from vehicle, use a self-powered test light or ohmmeter to perform the following tests. See illustration for pin numbers.

1. Clip one test lead probe on switch pin No. 3 which is grounded. With all switches in neutral position, pins No. 4 through 11 should have continuity to pin No. 3.
2. Push any one or all four of the switches forward. All odd numbered pins of the switches pushed forward should lose continuity to pin No. 3.
3. Push any one or all four switches rearward and all even numbered pins (4 through 10) of the switches pushed rearward should lose continuity to pin No. 3.
4. Remove test lead clip from pin No. 3 and connect it to pin No. 2. With all switches in neutral position, only pin No. 1 should have continuity to pin No. 2.
5. Push any one or all four switches forward and hold in that position. All odd numbered pins of switches pushed forward should have continuity to pin No. 2.
6. Pull any one or all switches rearward and hold in that position. All even numbered pins of the switches pulled rearward should have a continuity to pin No. 2.
7. If any one switch does not test as above, replace switch.
