LH Front Master Switch (2 Door)

Testing the power window master switch should be performed with the switch removed from the vehicle. Use a self-powered test lamp or an ohmmeter such as Rotunda Digital Volt Ohm Meter 007-00001 or equivalent.

Test Procedure

Except Ford Crown Victoria, Low Series (see below)

1. Clip one test lead probe on terminal 3 which is grounded.
2. With both switches in the NEUTRAL position, terminals 4 through 7 should have continuity to terminal 3.
3. Push both window switches forward and hold in that position (toward front of vehicle when in installed position).
Terminals 5 and 7 should lose continuity to terminal 3.
4. Push both window switches rearward and hold in that position (toward rear of vehicle when in installed position).
Terminals 4 and 6 should lose continuity to terminal 3.
5. Remove the test lead from terminal 3 and connect it to terminal 2 (hot feed pin).
Push both switches forward.
Terminals 5 and 7 should have continuity to terminal 2.
6. Pull both switches rearward.
Terminals 4 and 6 should have continuity to terminal 2.
7. If either switch does not test as stated, replace the complete switch assembly.
