1991 Cadillac Seville STSSECTION Power 6-Way Seat Adjuster Horizontal Actuator Adjustment
With seat adjuster assembly installed on seat or seat installed in body, horizontal movement (chucking) can be corrected by adjusting the horizontal actuator and pinion gear in tight to the adjuster lower track rack gear as follows:
- Operate seat to full-up position and about 3/4 full-forward position.
- Loosen horizontal actuator attaching screws. Using a large screwdriver, inserted as shown in Fig 1 , apply outward pressure on horizontal actuator (enough to equal 15 to 25 lbs. on horizontal actuator). At the same time energize horizontal switch to move seat fore and aft slightly; this helps seat the horizontal actuator pinion gear teeth tight to the lower track rack gear teeth and eliminate any free play between gear teeth.
- While maintaining outward pressure against horizontal actuator, tighten actuator attaching screws.
