the turn signal lever.
The turn signal lever pivots to actuate the dimmer
switch. The switch is activated when the outer end of the lever
is pulled toward the driver. As with the conventional foot
operated switch, when the switch is activated by a single
movement of the lever the high beams come on. When the
switch is activated again the lights will switch to low beam.
See the Steering Section for further details.
CORNERING LAMPS
Cornering lamps, optional equipment on B and G Series
only, are single filament lamps which illuminate when the
turn signal is engaged and the headlamp switch is on. The
cornering lamp will not blink and turns off when the turn
signal cancels. Current is available to the cornering lamps via
the front end harness and is fused through the fuse block.
SIDE MARKER LAMPS
These lamps are standard equipment on all cars. The
lamps become functional with the headlamp switch and are
designed to illuminate the side of the vehicle. The front side
marker lamps flash with the turn signals in operation while
the rear side marker lamps are illuminated only by the
headlamp switch. The circuit is fused with the tail, cornering
and park lamps.
DIAGNOSIS
Troubles in the lighting circuits are caused by loose
connections, open or shorted wiring, burned out bulbs, failed
switches, inadequate ground, or blown fuses. In each, trouble
diagnosis requires following through the circuits until the
source of difficulty is found. To aid in making an orderly
check, refer to the wiring diagrams shown at the end of
Section 8.
TURN SIGNAL SYSTEM
When a complaint is made involving the turn signal
system, it must first be determined whether the problem is
mechanical or electrical. If mechanical, the switch, column
casting, or cancel cam may be the cause, and one or more
of these should be repaired or replaced. If electrical, it must
be determined whether the switch or the chassis wiring is in
need of repair or replacement.
The wiring diagram, found at the end of this section,
should be used to trouble shoot the chassis and body wiring.
The nature of the customer complaint will generally
point to the problem area. Should it refer to the operation of
the turn signal lever, not cancelling from a turn, or not
returning from lane change, it is possible that the switch is
mounted loosely or off center.
Should lamps not light or flash or if one part of the
system itself is out, the problem would appear to be electrical
and could be caused by faulty chassis wiring, a partially
inoperative turn signal switch, burned out lamps, flashers or
