Power Window Circuit
NOTE:
Circuit testing is performed at driver-side power window switch.
- Remove driver-side switch from door trim panel. Disconnect power window switch harness connectors. Turn ignition on. Using a DVOM, check voltage between terminal No. 1 (Blue wire) of power window switch 2-terminal connector and ground. SeeFig 1 and Fig 2 . Battery voltage should be present.
- Turn ignition off. Using an ohmmeter, check continuity between ground and terminal No. 2 (Black wire) of power window switch 2-terminal connector. Continuity should exist. Check continuity between terminals No. 1 and 2 of power window switch 10-terminal connector. Continuity should exist.
- At power window switch 10-terminal connector, check continuity between terminals No. 1 and 7. Continuity should exist with right front switch in DOWN position and should not exist with switch in UP position.
- At power window switch 10-terminal connector, check continuity between terminals No. 2 and 7. Continuity should not exist with right front switch in DOWN position and should exist with switch in UP position.
- At power window switch 10-terminal connector, check continuity between terminals No. 3 and 4. SeeFig 1 and Fig 2 . Continuity should exist. Check continuity between terminals No. 3 and 7. Continuity not should exist with left rear switch in DOWN position and should exist with switch in UP position.
- At power window switch 10-terminal connector, check continuity between terminals No. 4 and 7. Continuity should exist with left rear switch in DOWN position and should not exist with switch in UP position.
- At power window switch 10-terminal connector, check continuity between terminals No. 5 and 6. SeeFig 1 and Fig 2 . Continuity should exist. Check continuity between terminal No. 7 and ground. Continuity should not exist.
- At power window switch 10-terminal connector, check continuity between terminals No. 9 and 10. Continuity should exist. Check continuity between terminals No. 7 and 9. Continuity not should exist with right rear switch in DOWN position and should exist with switch in UP position.
- At power window switch 10-terminal connector, check continuity between terminals No. 7 and 10. Continuity should exist with right rear switch in DOWN position and should not exist with switch in UP position.
- If continuity or voltage is not as specified in any of the previous steps, repair appropriate circuit as necessary. If all circuits are okay, check, repair or replace components as necessary.
