3 POWER SEATS
DESCRIPTION AND OPERATION
The four-way power seat mechan-
ism provides forward and rearward ad-
justment of the seat assembly; also,
up and down (tilting) movement for
the front of the seat. The seat tracks
are driven by a single reversible mo-
tor which transmits its power through
an electrically controlled transmission
and three flexible drive cables. A four-
way switch is located on the left side
of the seat and track assembly. This
switch directs power to the moJor and
transmission solenoids through two
relays.
The solenoids engage the drive ca..
bles which, in turn, drive the seat
tracks in the direction selected by the
driver. The front solenoid (blue wire)
engages the horizontal drive cables.
The rear solenoid (white wire) engages
the vertical drive assembly.
Both the control and power cir-
cuits are protected by a 20-ampere
circuit breaker which is mounted on the
starting motor relay in the engine
compartment.
WUR-WAY POWER SEAT DIAGNOSIS GUIDE
Refer to Wiring Diagram Manual Form 7795P-68 for locations of wiring harnesses. Schematics are shown in Group 19
of this manual.
CORRECTIVE ACTION
1. Check for voltage a t both ter-
minals of the circuit breaker. If no vol-
tage at both terminals of' the circuit
breaker, replace the.circuit breaker.
2. Disconnect the .switch feed wir-
ing connector (wire 51- black-white
stripe located under the seat). Check
for voltage at the female connector
(black-white stripe wire). If no voltage,
repair or replace the wire (Part of
Wiring Loom 14A697).

3. Inspect and tighten the ground
wire lug retaining screws.
4. Disconnect the switch wiring
multiple connector under the seat. Do
not disconnect the single wiring bullet
connector (wire 51-black-white stripe).
-
Operate the switch and check for
voltage a t the various terminals as fol-
lows: (Switch.side of the connector):
Forward-wire 306 (blue) and wire
168 (green-yellow stripe).
Rearward-wire. 306 (blue) and wire
2 16 (red-yellow stripe).
Up-wire 307 (white) and wire 216
(red-yellow stripe).
Down-wire 30' (white) and wire
168 (green-yellow stripe).
If voltage is not available at these
pins of the connector or if voltage is
available at pins other than stated, re-
place the switch assembly.
MALFUNCTION
MOTOR DOES NOT OPERATE
PROBABLE CAUSE
1. Defective 20-ampere circuit
breaker.
2. Open feed wire (black-white
stripe) between the 20-ampere circuit
breaker and the switch wiring connec-
tor.
3. Poor ground connection to the
floor pan or seat track assembly (un-
derneath the seat).
4. Defective switch assemhly.
