DELAY WIPER-ERRATIC TIMING WATER ENTERING WIPER MOTOR

A delay wiper may exhibit erratic timing in the "delay mode" if water drips onto and enters the wiper motor through the cover and/or the wiper terminal area.

The symptoms of water entry can also be:

1. Wiper may or may not park. 2. Washer pump may run continuously.

To correct this condition and prevent recurrence use the following procedure.

1. Allow wiper motor to dry completely.

2. Check the correct wiper operation in all modes after drying.

3. Apply duct tape to connector contacting the housing, connector and wiring as shown in the illustration.

4. Apply RTV sealant to lip of wiper cover as illustrated. Make sure RTV sealant is continuous to where the duct tape touches the housing.

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.
