CHATTERING WIPER BLADES OR BLADE WIPEABILITY (CLEANING PROCEDURE)

1982-1991 DE VILLES, FLEETWOODS, ELDORADOS, SEVILLES 1982-1988 CIMARRONS 1987-1991
ALLANTES
Some 1982-1991 DeVilles, Fleetwoods, Eldorados, and Sevilles; 1982-1988 Cimarrons; and 1987-1991 Allantes may experience a condition of
chattering and poor wipeability during windshield wiper operation.
This condition may be caused by the windshield glass and/or wiper blades becoming contaminated by insect residue, dirt, road grime, car wax, etc.
To repair this condition use the following procedure:
1.
Clean the windshield glass with GM P/N 1050011 (Bon Ami) glass cleaner or equivalent.
IMPORTANT:
The glass is clean when rinse water does not "bead up" but "sheets" across the entire glass surface. Multiple cleanings may be
required to remove all contaminants.
2.
Clean the wiper blades by using a cloth that has been saturated with full strength washer solution and wipe vigorously. Rinse the blades with
water after cleaning.
In addition, refer to Section 8E of the Service Information Manual for additional diagnosis of wiper chatter conditions.
