Master Window Switch
- Test procedures are performed using a self powered test light or ohmmeter. All test procedures are performed with switch removed from vehicle. See illustration for reference to pin numbers referred to in test procedures .
- Connect one test lead probe to pin three, which is grounded. With all switches in neutral position, pins four through eleven should have continuity with pin three.
- Push any one of all four switches forward. All odd numbered pins of switch pushed forward should lose continuity with pin three.
- Push any one of all four switches rearward and all even numbered pins (four through ten) of switch pushed rearward should lose continuity with pin three.
- Remove test lead probe from pin three and connect to pin two. With all switches in neutral position, only pin one should have continuity with pin two.
- Push any one of all four switches forward and hold in that position. All odd numbered pins of switch pushed forward should have continuity with pin two.
- Push any one of all four switches rearward and hold in that position. All even numbered pins of the switch pushed rearward should have continuity with pin two. If any one switch does not test correctly, as previously outlined, switch must be replaced.
