BHE090358000W07

3

Driver-side front window reverses even though the glass does not encounter a foreign object while it is going up in automatic mode.

POSSIBLE CAUSE

• Too much driver-side front window friction resistance: Steps 1-5
• Short to ground in position sensor 1 and sensor 2 signal from wiring harness (between power window main switch and driver-side front power window motor), inner driver-side front power window motor, or inner power window main switch: Steps 6, 7
