GENERAL INFORMATION
INTRODUCTION
Power seats can be adjusted in eight directions; up,
down, forward, back, tilt forward, or tilt rearward.
Four reversible motors and a transmission located on
the seat tracks provide the various seat movements.
The electrical circuit is protected by a 40 amp fuse in
the Power Distribution Center (PDC) and a 30 amp
circuit breaker located in the wire harness under the
driver's seat.
DIAGNOSIS AND TESTING
DIAGNOSTIC PROCEDURES
Before testing the seat functions, verify that the
battery is fully charged and the terminals cleaned
and tightened to ensure proper connections. If the
battery is not fully charged, refer to Group 8A Bat-
tery for proper testing procedures.
The following test will determine if the circuit is
complete through the body harness to the switch:
Using a voltmeter, verify the condition of the power
seat circuit breaker located under the driver's seat.
The circuit breaker also protects the passenger side
power seat track circuit. Check both sides of the cir-
cuit breaker connector for voltage, on the wire side.
• If not OK replace circuit breaker.
• If battery voltage is detected on both sides of the
circuit breaker. Refer to Seat Motor in the Diagnostic
and Testing in this section.

• If seat motors test OK, refer to the Seat Switch
in the Diagnostic and Testing in this section.
• Refer to Group 8W Wiring Diagrams for wire
circuit information.
SEAT MOTORS
(1) Remove power seat switch from seat. Refer to
Group 23 Body for procedures.
(2) Disconnect wire connector.
(3) Using a voltmeter check for battery voltage at
Pin 5. Using an ohmmeter, check Pin 1 for ground.
(4) To test the seat motors, refer to (Fig. 1) and
verify proper seat responses. Using two jumper
wires, connect one to a battery supply and the other
to a ground. Connect the other ends to the seat wire
harness connector as described in (Fig. 1). If any
motor fails to operate, check wire connectors to the
motor. If not OK, repair as necessary. If OK, replace
seat motor/track assembly.
POWER SEAT SWITCH
(1) Remove power seat switch from seat. Refer to
Group 23 Body for procedures.
(2) Using an ohmmeter, perform the switch conti-
nuity tests in (Fig. 2). If there is no continuity at any
of the switch positions, replace switch.
