DRIVER POWER SEAT SWITCH (Continued)
tion 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 must not be allowed to con-
tinue, or the motor may be damaged. See the owner's
manual in the vehicle glove box for more information
on the power seat switch functions and the seat
adjusting procedures.

seat switch connector for continuity to ground. It
should be present, If OK go to Step 3 , If NOT OK
repair the open ground circuit as required.
(3) Using an voltmeter, check pin #5 of the power
seat switch connector for approx. 12v. It should be
present, If OK go to Step 4 , If NOT OK repair the
open voltage supply circuit as required.
