Power Window Switch Circuit (Driver's Side Switch)
NOTE:
Circuit testing is performed at drivers' side power window switch.
- Remove switch from door trim panel. Disconnect power window switch harness connectors. Using a DVOM, check voltage between power window switch 2-terminal connector, terminal No. 1 (Blue wire) and ground, with ignition switch in ON position. SeeFig 1 . Battery voltage should be present.
- Using an ohmmeter, check continuity between power window switch 2-terminal connector, terminal No. 2 (Black wire) and ground. Continuity should exist. Check continuity between power window switch 10-terminal connector, terminals No. 1 and 2. Continuity should exist.
- Check continuity between power window switch 10-terminal connector, terminals No. 1 and 7, with right front power window switch in DOWN position, then in UP position. Continuity should exist with switch in DOWN position and should not exist with switch in UP position.
- Check continuity between power window switch 10-terminal connector, terminals No. 2 and 7, with right front power window switch in DOWN position, then in UP position. Continuity should not exist with switch in DOWN position and should exist with switch in UP position.
- Check continuity between power window switch 10-terminal connector, terminals No. 3 and 4. SeeFig 2 . Continuity should exist. Check continuity between power window switch 10-terminal connector, terminals No. 3 and 7, with left rear power window switch in DOWN position, then in UP position. Continuity not should exist with switch in DOWN position and should exist with switch in UP position.
- Check continuity between power window switch 10-terminal connector, terminals No. 4 and 7, with left rear power window switch in DOWN position, then in UP position. Continuity should exist with switch in DOWN position and should not exist with switch in UP position.
- Check continuity between power window switch 10-terminal connector, terminals No. 5 and 6. SeeFig 2 . Continuity should exist. Check continuity between power window switch 10-terminal connector, terminal No. 7 and ground. Continuity should not exist. Check continuity between power window switch 10-terminal connector, terminals No. 9 and 10. Continuity should exist.
- Check continuity between power window switch 10-terminal connector, terminals No. 7 and 9, with right rear power window switch in DOWN position, then in UP position. Continuity not should exist with switch in DOWN position and should exist with switch in UP position.
- Check continuity between power window switch 10-terminal connector, terminals No. 7 and 10, with right rear power window switch in DOWN position, then in UP position. Continuity should exist with 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 appropriate component(s) as necessary.
