DIRECTIONAL SIGNAL SWITCH DIAGNOSIS
• loose connections, and,
• burned out lamps.
A flashing rate, approximately twice the normal
rate, usually indicates a lamp has shorted in
the circuit.
If a three-lamp flasher is installed in a vehicle
having only two lamps per side, the lamps will
light but will not flash.
If a two-lamp flasher is used on a vehicle having
three lamps (trailer towing), the higher current
draw will cause the lamps to flash too fast.
If there is no signal at any front, rear, or indicator
lamp, check the fuse.
If the fuse is not defective, substitute a flasher
which is known as not defective.
If the replacement flasher does not remedy the
problem, check the signal system wiring
connections at the fuse and at the steering
column connector.
If the brake stoplamps function properly, the rear
signal lamps are not defective.
NOTE: The directional signal flasher is attached
directly to the fuse panel.
