Condition
Some owners may comment that the windshield wiper arms or blades intermittently stop (park) in a vertical position, rather than at the base of the
windshield, when the wiper switch is placed in the "OFF" position. They may comment that the condition usually occurs after a heavy rain or car wash
followed by cold (below freezing) temperatures.
Cause
During heavy rains or car washing environments, water entering the cowl (plenum) through the leaf screen may accumulate and later freeze on the
depressed park actuator arm which is located on the bottom side of the wiper motor crank arm. If this occurs, the actuator arm may not come in contact
with the metal tab on the wiper motor mounting bracket when the wiper switch is turned off, resulting in the arms parking in a vertical position.
Correction
To correct this condition, replace the wiper motor crank arm with P/N 12367235 and install water deflector P/N 10411068. Also, additional sealing
material must be added to the crank arm cover to improve the deflection and channeling of the water away from the crank arm assembly.
Use the following service procedure when replacing the crank arm assembly, installing the new water deflector/retainer and to improve the sealing of the
crank arm cover.
Important:
Some vehicles may have already had the wiper motor crank arm replaced. These vehicles can be identified by the barrier material already applied
over the hole in the crank arm cover. See Figure 3. If the crank arm cover already has the barrier material applied, then it is only necessary to install
the new water deflector. Do not replace the crank arm assembly on those vehicles. If there isn't any barrier material already applied over the hole in
the crank arm cover, then the crank arm assembly must be replaced and the new water deflector installed.
