# CONTINUOUS WIPER OPERATION REPLACE BENT DRIVE PAWL

#### 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.

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.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
