Windshield wiper
Inoperative. 1. Turn ignition switch to RUN
and wiper switch clockwise
to HIGH SPEED. Ground a
12 Vdc test lamp and touch
probe to wiper or switch
terminal H.
2. If lamp lights, turn wiper
switch to LOW, leave
wiring connected to wiper
motor, and connect jumper
wire from motor to ground.
3. If lamp doesn’t light, circuit
breaker may be stuck in
the open position, it may
be oscillating between
open and closed due to a
short in the circuit, or it
may be in its normally
closed condition.
If lamp lights, continue with
step 2; if lamp doesn’t light,
continue with step 3.
If wiper runs, repair open in
ground strap; if wiper doesn’t
run, problem is in motor (refer
to paragraph 10.10.3).
If open, replace circuit
breaker. If oscillating, check
for high amperage draw due
to a short in wiring or motor. If
circuit breaker is closed,
repair open in line 32 between
circuit breaker and wiper
motor or repair or replace
wiper motor.
