This PI was superseded to update model years. Please discard PIC3724A.

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.


Power windows may reverse during the express close function. This may be due to the door window contacting the A pillar weather-strip. This contact creates friction which causes the window to reverse as if it was obstructed.


Adjust door glass by slightly tipping the top of the window outward. Adjust in small increments so not to induce a wind noise or water leak. Reinitialize power windows and re-evaluate window operation.

Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
