SYMPTOM/CONDITION: Fore-aft function does NOT work when actuating the seat switch. DIAGNOSIS: 1) Put seat in position for inspection. 2) Disconnect seat wire harness motor connector from the fore-aft motor on the seat adjuster, wait 10 seconds, and reconnect. 3) Verify function of the fore/aft adjuster. Step 1. Open 2nd row door and function rear seat cushions up to stowed position. Step 2. Adjust the driver front seat to the full up position. Use switches on the side shield to move power seat fully up. Step 3. Remove the 4 bolts that hold the seat to the truck floor and discard. The bolts have lock patch that is not reusable. Step 4. Lay the seat down so its laying on its back so the underside of the seat is easily accessible. Step 5. Remove the fore/aft wire harness motor connector from the fore/aft motor (back right of the seat adjuster). Push on the tab to remove the motor wire harness connector from the motor. Leave disconnected for 10 seconds. Step 6. Reconnect the fore/aft wire harness motor connector to the fore/aft motor. Push / Pull / Push the connector with fingers to ensure the wire harness connector is fully seated to the fore/aft motor connector. Step 7. Before assembling the seat back to the truck floor, cycle the seat to check that the motor is working properly by pressing the fore/aft switch. If fore/aft motor does not function, please refer to Replacement Procedure below. Step 8. If the seat is working properly, carefully reassemble the seat back to the truck floor using the four new bolts. Use a torque wrench to verify 47 Nm. Step 9. *Note: Checking the passenger seat will be the same procedure as the driver seat. REPLACEMENT PROCEDURE  Only for seats rejected after inspection. Replace Power Seat Adjuster per MOPAR service part replacement instructions. MOPAR Part Numbers: 68455847AA, 68455848AA, 68455849AA"

prior to replacing seatbelt please inspect for debris and any build up on the webbing and DRing. If evidence of debris and build up, please clean seatbelt webbing or turning loop as described below. Seat Belt Maintenance: Do not bleach, dye or clean the belts with chemical solvents or abrasive cleaners. This will weaken the fabric. If the belts need cleaning, use a mild soap solution or lukewarm water. Do not remove the belts from the vehicle to wash them. Dry with a soft cloth. Sun damage can also weaken the fabric. Replace the belts if they appear frayed or worn or if the buckles do not work properly. NOTE: If the belts retract slowly, inspect the upper turning loop for soiling. If soiling is present, clean with a wet soft cloth until all residue is removed.
