DESCRIPTION
A 3 armature permanent magnet reversible motor is coupled
through cables to rack and pinion assemblies, located in the tracks.
This system provides 6 different movement directions. Circuit is
protected by a 30-amp circuit breaker on the fuse block.
TESTING
PRELIMINARY CHECKS
Ensure battery is fully charged and all electrical
connections are clean and tight. Turn on dome light. Apply switch to
the inoperative position. If dome light dims, seat motion is
attempting to function, indicating mechanical failure. Check and
repair as necessary. If dome light does not dim, proceed with the
following tests.
HARNESS VOLTAGE
Disconnect switch harness connector, located under seat.
Connect ground lead of test light to terminal No. 2. Touch other lead
of test light to terminal No. 1. See Fig. 1. If test light comes on,
circuit is good. If test light does not come on, check circuit breaker
and harness. If harness and circuit breaker checks good, perform drive
motors check.

DRIVE MOTORS
Page 1006 of 1378
Rear Motor
Disconnect switch harness connector. Connect a covered jumper
wire between terminal No. 1 and 5. See Fig. 1. Connect a second
covered jumper wire between terminal No. 2 and 6. If motor does not
operate, reverse jumper wire at terminal No. 5 and 6. If motor still
does not operate, either harness or complete 3 motor assembly is
defective.
Center Motor
Disconnect switch harness connector. Connect a covered jumper
wire between terminal No. 1 and 3. See Fig. 1. Connect a second
covered jumper wire between terminal No. 2 and 4. If motor does not
operate, reverse jumper wire at terminal No. 3 and 4. If motor still
does not operate, either harness or complete 3 motor assembly is
defective.
Front Motor
Disconnect switch harness connector. Connect a covered jumper
wire between terminal No. 1 and 7. See Fig. 1. Connect a second
covered jumper wire between terminal No. 2 and 8. If motor does not
operate, reverse jumper wire at terminal No. 7 and 8. If motor still
does not operate, either harness or complete 3 motor assembly is
defective.
NOTE: No further testing information is available from
manufacturer.
REMOVAL & INSTALLATION
MOTOR
CAUTION: Use care to avoid bending drive cables during removal.
NOTE: Whenever maintenance of motor, cable and housing assemblies
or transmissions is necessary, they must be synchronized to
ensure easy and proper operation. Refer to manufacturer for
proper procedure.
Removal & Installation
Remove seat assembly. Lay seat assembly on its back. Remove
motor mounting screws. Disconnect housings and cables from motor
assembly and remove motor. To install, reverse removal procedure.

Indicates that Selec-Trac transfer case is in part time 4WD
(high or low range).
FULL TIME 4WD INDICATOR LIGHT
Indicates that Selec-Trac transfer case is in full-time 4WD
(4x4 FULL TIME).
PART TIME 4WD INDICATOR LIGHT
Indicates that Selec-Trac transfer case is in part time 4WD
