Driver's Master Window Switch

  1. Voltage Measurements

    Measure voltage by backprobing between master window switch appropriate terminal and ground. Leave master window switch connected to wiring harness, unless indicated. See POWER WINDOW SWITCH VOLTAGE TEST (1 OF 2)  table. If voltage is as specified, go to CONTINUITY CHECKS. If voltage is not as specified, repair affected circuit. See WIRING DIAGRAMS .

    (1) For terminal locations, see Figure.
    (2) Tests are made with master switch disconnected from vehicle wiring harness.

  2. Continuity Checks

    With master window switch still connected, check continuity by backprobing between master window switch terminal No. 10 and ground. Disconnect master window switch and check continuity between master window switch terminal No. 9 and ground. Continuity should be present at both measurements at all times. If continuity is not present at either measurement, repair affected circuit. See WIRING DIAGRAMS . If continuity is present at both measurements, circuits are okay at this time.
