LIGHT TRUCK 1986 F-150/350, BRONCO
ISSUE:
Windshield wiper blades that skip and leave unwiped areas on the windshield when the vehicle is driven at or above 35 mph/56 km/h may be
caused by the wiper arm assembly. The latch component on the wiper arm assembly may restrict downward pressure of the arm on the
windshield.
ACTION:
To correct this, install two (2) new wiper arm assemblies (E4TZ-17526-C) using the following service procedure.
1.
Switch the wiper arm and blade assemblies from right to left.
2.
Road test the vehicle at speeds above 35 mph/56 km/h with the windshield wipers turned on. Use windshield washer spray if required.
3.
If the condition still exists, replace both wiper arm assemblies. DO NOT replace the wiper blade(s). Refer to the 1986 Light Truck Shop Manual,
Volume A, Section 35-60 for the removal and installation of the wiper arm assemblies.
