SERVICING PROCEDURES
Test
Before any testing is attempted, the battery should be
fully charged and all connections and terminals cleaned
and tightened to insure proper continuity and grounds.
With the dome light on, apply the switch in the direc
tion of failure. If the dome light dims, the seat may be
jamming. Check for binding. If the dome light does not
dim, then proceed with the following electrical tests.
(1) Disconnect wiring harness at connector under
seat. Connect 12 volt test lamp between red and black
wire in female connector on harness. If test lamp lights,
harness to seat is good. If test lamp does not light, check
as follows:
(a) Current at fuse panel circuit breaker.
(b) Continuity in red wire between fuse panel
and harness connector under seat.
(c) Continuity in black wire and proper con
nection to ground.
(2) Remove test lamp and connect harness.
(3) Remove switch from seat harness.
(4) To check rear motor, connect covered jumper
wire between red terminal in center section (fig. 3M-10)

wire between red terminal of center section and either
white or tan connection in center section. Connect sec
ond covered jumper wire between black terminal in cen
ter section and open connection in center section. If

If motor still does not operate, either harness or com
plete three motor assembly should be replaced.
(6) To check front motor, connect covered jumper
wire between red terminal in center section and either
green or yellow connection in rear section. Connect sec
ond covered jumper wire between black terminal in cen
ter section and open connection in rear section. If motor
does not operate, reverse jumpers in the section. If mo
tor still does not operate, either harness or complete
three motor assembly should be replaced.
