DIRECTIONAL SIGNAL SWITCH
The directional signal switch is a self-contained unit which incorporates
the hazard warning switch and the lane changing signal.
The hazard warning circuit is activated by a push-pull switch which is
located on the right side of the steering column, opposite the directional
signal lever. The switch knob must be pulled to cancel circuit.
The lane changing circuit is activated by holding the directional signal
lever in the first detent position; there is no lock in or cancelling device
in this position.
See Section 9 "Steering" for all servicing procedures.

GENERAL DESCRIPTION
The wiper motor assembly consists of compound wound
12 volt D.C. motor, gear reduction mechanism and
parking switch enclosed in a common die cast housing.
The armature has a worm shaft which drives a gear and
shaft assembly. A crank arm, which is attached
externally to the gear shaft, operates the linkage which
activates the blades.
The wiper motor is equipped with an internal circuit
breaker mounted on the motor brush plate which
protects the motor from overheating.
Figure 16 shows the assembly of the washer pump to the
wiper motor.
