Description & Operation

WARNING: Vehicles are equipped with air bag supplemental restraint system. Before attempting ANY repairs involving steering column, instrument panel or related components, see SERVICE PRECAUTIONS and DISABLING & ACTIVATING AIR BAG SYSTEM in appropriate AIR BAG RESTRAINT SYSTEMS article.

The optional six-way power seat system uses a screw-type drive for seat adjustment. It consists of three reversible armature motors, switch assembly, and vertical and horizontal screw drives. The six power functions are actuated by a single control handle on the slide lifter switch assembly. The six-way power seat provides the following adjustments:

UP

Front and rear motors are energized, raising the seat.

DOWN

Polarities of the front and rear motors are reversed, lowering the seat.

FRONT TILT

Front motor is energized, raising or lowering the front of the seat.

REAR TILT

Rear motor is energized, raising or lowering the rear of the seat.

FORWARD

Forward motor is energized, moving the seat forward.

BACKWARD

Polarity of the forward motor is reversed, moving the seat backward.

Voltage is applied at all time to the Power Seat Switch through the POWER SEAT fuse of the Interior Fuse Panel. The Power Seat Switch consists of six switches and three motors, operated through a single control lever that is mounted on the lower left side of the driver's seat. The three motors are: the Front Height Motor, which drives the front of the seat up and down; the Rear Height Motor, which drives the rear of the seat up and down; and the Forward/Rearward Motor, that drives the seat forward and backward.

Moving the control lever in the desired direction of seat movement determines how current is applied through the Power Seat Switch. For example, when the lever is pulled straight up, both UP contacts of the Height Motors in the Power Seat Switch are closed. Under these conditions both Height Motors receive current through the closed UP contacts and are grounded to through the DOWN contacts. See WIRING DIAGRAMS .
