Condition
Some customers may comment that the front driver and/or passenger power seat up and down adjustments are inoperative. They may also comment that
the seat binds or sticks when in the full up or down tilt position.
Cause
The cause may be the nylon stop washer (1) being compressed into the lead tilt adjuster screw when in the full up or down tilt position.
Correction
Install new stops using the procedure below.
1.
Verify that the condition is caused by the tilt adjuster screw binding or locked into the full tilt up or down position.

Open the hood.
3.
Connect a battery charger. Refer to Battery Charging in SI.
4.
Toggle the front seat switch down (1) and up (2) with the seat unoccupied. If the seat moves up and down, then proceed to Step 5.
