This PI was superseded to update model years and Recommendation/Instructions. Please discard PIT4228.
The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern:
Some owners may comment that their passenger window express down feature is inoperative.
Recommendation/Instructions:
The passenger window express down feature is no longer a standard option like on the previous models. Models equipped with either Memory Seats (RPO AN3) and/or Power Folding Mirrors (RPO DL3) will have the passenger window express down feature. If the vehicle does not have either of the RPOs listed above, this is a normal operating characteristic.
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.
