(GAUGE AT
NORMAL
OPERATING
PRESSURE)
NOTE
If any component within the
pneumatic windshield wiper assembly
is found to be damaged, replace the
entire pneumatic windshield wiper
assembly with the electrical
windshield wiper assembly
(WP 0240 00). Work packages listed
in this malfunction refer to the
installation of the electrical
windshield wiper assembly.

to build to normal operating
pressure.
2. Operate windshield wipers and
inspect lines and hoses for leaks.
Test 1. Check windshield wiper motor
supply line (9) pressure.
1. Compress clamp (8) and
disconnect windshield wiper
supply line (9) from tee (7).
