Power Seat Switch - Vehicles may be equipped with a driver side six-way power seat switch. The power seat
switch has a paddle-type lever mounted on the outboard seat side shield. Movement of the seat cushion mimics
the action of the switch paddle.

OPERATION

POWER SEAT SYSTEM

The power seat system receives battery current through a fuse in the Totally Integrated Power Module (TIPM)
so that the power seats remain operational, regardless of the ignition switch position.

When a power seat switch is actuated, a battery feed and a ground path are applied through the power seat
switch contacts to the appropriate motor or motors. The motor and drive unit operate to move the seat in the
selected direction until the switch is released, or until the travel limit of the power seat track is reached. When
the switch is moved in the opposite direction, the battery feed and ground path to the motor is reversed through
the switch contacts. This causes the motor to run in the opposite direction.

DIAGNOSIS AND TESTING

POWER SEAT SYSTEM

Operate the power seat switch and move the seat in all directions. The seat should move in each of the selected
directions.

If the power seat adjuster fails to operate in more than one direction, proceed as follows:

1. Inspect the power seat track adjuster motors to ensure the electrical connectors are fully seated to the

motors. If OK, go to step 2. If not OK, connect the electrical connector to the fully seated position.

2. Check the power seat fuse in the Totally Integrated Power Module (TIPM). If OK, go to step 3. If not

OK, replace the inoperative fuse.

3. Remove the power seat switch from the seat cushion side shield. See REMOVAL. Check for battery

voltage at the fused B(+) circuit cavity of the power seat switch wire harness connector. If OK, go to step
4. If not OK, repair the open circuit to the TIPM as required.

4. Check for continuity between the ground circuit cavity of the power seat switch wire harness connector

and a good ground. There should be continuity. If OK, go to step 5. If not OK, repair the open circuit to
ground as required.

5. See DIAGNOSIS AND TESTING. If the switch tests OK, check the wire harness between the power

seat switch and the motor. If the circuits check OK, replace the faulty power seat track assembly. If the
circuits are not OK, repair the wire harness as required.

DESCRIPTION

SEAT SWITCH

The driver power seat can be adjusted in six different ways using the power seat switch. The power seat switch
(2) is located on the lower outboard side of the seat cushion (1) on the seat cushion side shield (3). The power
seat system incorporates a seat switch with a seat cushion control paddle.

The individual components in the power seat switch assembly cannot be repaired. If the switch is damaged or
inoperative, the entire power seat switch must be replaced.

OPERATION

SEAT SWITCH

When a power seat switch is actuated, a battery feed and a ground path are applied through the switch contacts
to the power seat track adjuster motor. The selected adjuster motor operates to move the seat through its drive

unit in the selected direction until the switch is released, or until the travel limit of the adjuster is reached. When
the switch is moved in the opposite direction, the battery feed and ground path to the motor are reversed through
the switch contacts. This causes the adjuster motor to run in the opposite direction.

No power seat switch should be held applied in any direction after the adjuster has reached its travel limit. The
power seat adjuster motors each contain a self-resetting circuit breaker to protect them from overload. However,
consecutive or frequent resetting of the circuit breaker may result in motor damage.

1. Disconnect and isolate the battery negative cable.

2. Remove the power seat switch from the power seat. See REMOVAL.

3. Use an ohmmeter to test the continuity of the power seat switch. Refer to POWER SEAT SWITCH

CONTINUITY. If not OK, replace the faulty power seat switch. If switch tests OK. See DIAGNOSIS
AND TESTING.
