Solenoid #1, Fig. 16-60, controls the vertical
movement of the rear edge of the seat. Solenoid
#2 controls the horizontal movement of the seat.
Solenoid #3 controls the vertical movement of the
front edge of the seat. In addition to six seat ad-
juster drive cables at the transmission assembly,
a motor drive cable is installed from the motor
to the transmission assembly, Fig. 16-60. When
one of the control switch buttons is actuated, the
motor and one of the solenoids are energized
simultaneously. The solenoid plunger engages the
large gears with a driving gear. The driving gear
rotates the large gears which rotates the drive
cables and operates both adjusters. When the
switch contacts are opened, a spring returns the
solenoid plunger to its original position, disen-
gaging the large gears from the driving gear.
