POWER WINDOW SWITCH CIRCUIT (DRIVER'S SIDE SWITCH)

Note. Circuit testing is performed at drivers' side power window switch.

  1. 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. (Scheme 1) Battery voltage should be present.
  2. 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.
  3. 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.
  4. 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.

  3. Check continuity between power window switch connector terminals No. 2 and 4. Continuity should exist. Using a DVOM, check voltage between power window switch connector terminal No. 3 and ground, with ignition switch in ON position, and lock switch in ON position, then in OFF position. Voltage should not be present with switch in ON position. Battery voltage should be present with switch in OFF position.
  4. Check continuity between power window switch connector terminal No. 5 and ground. Continuity should exist. Using a DVOM, check voltage between power window switch connector terminal No. 5 and ground, with ignition switch in ON position, and appropriate power window switch at driver's side power window switch in OFF position, then in UP position. Voltage should not be present with switch in OFF position. Battery voltage should be present with switch in UP position.
  5. 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.

POWER WINDOW MOTOR CIRCUIT (DRIVER'S SIDE SWITCH)

  1. Remove driver's door trim panel and remove power window switch assembly. Disconnect driver's side power window switch connector for appropriate power window. Apply battery voltage to specified connector terminal and ground specified connector terminal. See «POWER WINDOW MOTOR CIRCUIT TEST (DRIVER'S SIDE SWITCH)»(ref-35257-S38852070372001010900000). For connector terminal locations (Scheme 1)and (Scheme 2).
  2. Power window should operate unless it is already at maximum travel. Reverse test leads. Power window should operate in opposite direction. If power windows operate as specified, wiring circuits are okay. If power windows do not operate as specified, repair appropriate circuit as necessary. If circuit is okay, check appropriate power window motor and replace as necessary. See «POWER WINDOW MOTOR TEST»(ref-35257-S11007338742001010900000) under TESTING.
