Front Seat Adjuster Replacement Six-Way Power
Removal Procedure
- If one side of the seat adjuster is not working, perform the following procedure:
1.1. | The horizontal drive motor (1) and drive cables (4) are
located at the front of the seat. Verify that both cables are straight. If a cable
is bent an end will be pulled out of the drive motor or drive screw. Straighten the
cable. You may have to toggle the seat switch to get the cable ends to properly seat. |
1.2. | Run the seat forward until the seat removal bolts are accessible. |
1.3. | Once the seat is removed examine the cables to assure that no damage has
occurred. |
1.4. | The two sides of the seat adjuster will now be out of sync. Align these
sides or the adjuster may be noisy and the motor may overheat and fail. |
Use the following steps to align the adjuster:
1.4.1. | Tip the seat rearward. |
1.4.2. | Reconnect the adjuster to the power switch. |
1.4.3. | Run the seat adjuster rearward until the drive bracket (3) and the anchor
bracket (2) are together on one side of the adjuster. |
1.4.4. | Disconnect the drive cable on that side and run the opposite side rearward
until its brackets touch. |
1.4.5. | Re-attach the cables (4) to the motor and verify that the cables are
straight between the motor (1) and the drive brackets (3). |
- If the power seat motor is not operable,
and the bolts that secure the adjuster to the floor pan are not accessible, perform
the following procedure:
2.1. | From the front of the seat, disconnect both drive cables at the horizontal
drive motor (2), which is located at the front of the seat adjuster. |
2.2. | Attach a drill motor to a drive cable (1). |
2.3. | Alternately run both sides of the adjuster forward until the seat removal
bolts are accessible. |
