Front Passenger Side Power Window Auto Up / Down Function does not Operate with Front Passenger Side Power Window Switch: Procedure

1. Turn the engine switch on (IG).
2. Operate the power window regulator switch assembly for 2 seconds or more.
3. Check the blinking pattern of the LED illumination. Compare the blinking pattern with the following illustration.

   HINT: 

   If there is a malfunction in the pulse sensor, manually operate the power window regulator master switch assembly or power window regulator switch assembly will cause the power window regulator master switch assembly or power window regulator switch assembly LED illumination to blink. The LED illumination continues to blink for 45 seconds or until the engine switch is turned off. After 45 seconds, the power window regulator master switch assembly or power window regulator switch assembly LED illumination remains on.
