PTC operation is a function that prevents overloading of the power window regulator by stopping the motor. PTC operation activates when the power window regulator switch is operated for a predetermined amount of time.

1. Pull up and hold the power window regulator switch for more than 90 seconds. Then release the switch.
2. Check that pressing the switch does not move the window.
3. Wait until 60 seconds have passed since the switch was released in the first step. Check that pressing the switch results in normal window movement.
