Circuit/System Testing

  1. Ignition OFF, disconnect the harness connector at the master window switch.
  2. Test for less than 1 ohm of resistance between the ground circuit and ground.
    • If greater than 1 ohm, test the ground circuit for an open/high resistance.
  3. Ignition ON, test for voltage on the voltage circuit to the window switch.
    • If no power is present, test the voltage circuit for an open/high resistance.
  4. If all circuits test normal, test or replace the master window switch.
