SUBJECT:
WINDSHIELD WIPER CONTINUOUS OPERATION
MODELS AFFECTED: 1985 FLEETWOODS AND DEVILLES
Some 1985 Fleetwoods and Devilles may experience a condition of inoperative or continuous low speed wiper operation after snowfalls or ice storms.
This condition can be caused by a build-up of packed snow or ice in the park area of the wiper arm. When this build-up occurs, it may inhibit the wiper
arm causing the drive pawl inside the wiper motor to bend.
FIGURE 1 - DRIVE PAWL AND PARKING SWITCH DRIVE PAWL SLOT
To determine if the parking pawl is bent, disconnect the four-terminal connector attached to the wiper cover and then remove the wiper cover. Inspect the
pawl to see if it is bent; a bent drive pawl will be obvious as it will not fit all the way into the notch in the parking switch, see Figure 1, or it may be
bound inside of the parking switch. If the pawl is bent, also inspect for damaged parking switch and gear assembly. NOTE: When reinstalling the wiper
cover, refer to Figure 2-27 in the 1985 Fisher Body "C" Style Service Manual.
If the drive pawl is damaged, shaft assembly (P/N 22048614) should be used to repair the wiper motor. To install the new shaft assembly, follow
instructions in Section 2 of the Fisher Body Service Manual for "C" style cars under gear replacement.
