Condition

Some customers may comment that the front driver power seat will not move forward or backward.

Cause

This condition may be caused by the horizontal motor drive cable breaking apart.

Correction

Replace the horizontal motor drive cable using the procedure below.

  1. Remove the front driver seat from the vehicle. Refer to the Bucket Seat Replacement procedure in SI.
  2. Place the seat upside down on a clean workbench.

  3. Object Number: 1977801  Size: SH
  4. Locate the horizontal motor drive cable (1) mounted in the motor bracket (2).

  5. Object Number: 1977802  Size: SH
  6. Using a standard screwdriver, carefully pry up on the plastic drive cable housing to unsnap from the motor bracket.
  7. Remove the drive cable from the horizontal motor and transmission. Ensure that all cable fragments are removed before proceeding.

  8. Object Number: 1977803  Size: SH
  9. Using a metric ruler, measure from the front end of the upper rail (1) to the front end of the lower rail (2) on the inboard track section.

  10. Object Number: 1977804  Size: SH
  11. Using a metric ruler, measure from the front end of the upper rail (1) to the front end of the lower rail (2) on the outboard track section.
  12. If the measurements are within 3 mm (0.12 in) from each other, proceed to step 10. If the difference in the measurements is greater than 3 mm (0.12 in), the track section must be timed. Proceed to step 9.
  13. Horizontally power the seat (fore or aft) to cause the outboard track section to get a measurement within 3 mm (0.12 in) of the inboard track section. The track sections are now in time.

  14. Object Number: 1977805  Size: SH
  15. Insert one end of the new drive cable into the horizontal motor until fully seated. If the seat is a memory seat, the longer unflocked end of the drive cable will be inserted into the motor.
