Side Window(s) Open After One-Touch Closing

If you receive customer reports in the above model vehicles of the side windows opening slightly after closing with the one-touch feature, check for a

mechanical problem by following the below steps. In most cases, the reason for this is that the window mechanism detects a mechanical resistance

and opens approximately 5 cm as designed. To correct, the source mechanical resistance needs to be removed.

1. Check window guide - The dimension between the front and rear window guides (window frame) must be identical at the top and bottom and

the door window must have a constant 1 mm of play (clearance) from top to bottom.

2. Check door window - The door window must move with smoothness from top to bottom. Make sure the door window slots easily and

completely into the upper (horizontal) window guide.

3. Check window guide - In the upper, front and rear corners, the window guide must be seated correctly at right angles or seated properly in the

corners.

4. Re-normalize power windows - Hold down power window switch at the first detent for longer than 1 second after the window has closed. It is

possible to de-normalize the power window using the HHT and then re-normalize it as described above.

If none of these measures is successful, the radius of the door window should also be checked.
