Campaign - Windshield Washer Pump Failure: Overview

NUMBER: 86-C-03

GROUP: 8-Chassis Electrical

DATE: June, 1986

SUBJECT: WINDSHIELD WASHER PUMP FAILURE

MODELS: 1985 and 1986 C/K MODEL TRUCKS

General Motors has become aware of a condition on 1985 and some 1986 C/K Model Light Duty Trucks where the windshield washer pump motor located behind the plastic reservoir, may become corroded and shorten the life of the motor. A crimp between the inner and outer fender could divert water onto the pump during a car wash or heavy rain or overfilling of the washer jar could cause drenching of the pump motor, thus causing the pump motor to corrode. To prevent the possibility of this condition occurring, involved owners will be mailed a plastic shield to be installed on the reservoir to prevent the possibility of water entering the pump. In addition, a special policy adjustment will be provided on the washer pump for 5 years from vehicle in-service date on all involved vehicles.
