Power Window System Current Test

NOTE: System circuit breaker opens 4-40 seconds after window operation stops. Ensure circuit test is performed before circuit breaker operates.
  1. Disconnect connector from driver's side power window switch. Connect positive lead of ammeter to driver's side power window switch connector (harness side) terminal No. 6. See Figure.
  2. Connect ammeter negative lead to negative terminal of 12-volt battery. Connect jumper wire from positive battery terminal to driver's side power window switch connector (harness side) terminal No. 13.
  3. While lowering driver's side window, current should be about 7 amps. When window operation is stopped, current should increase to about 14.5 amps or more. If current is as specified, replace driver's side power window switch. If current is not as specified, check and repair appropriate circuit.
