WINDSHIELD STREAKING REPAIR PROCEDURE

SUBJECT: WINDSHIELD STREAKING (REPAIR PROCEDURE)

VEHICLES AFFECTED: 1988 PONTIAC BONNEVILLE "H" MODELS

A condition of windshield streaking from wiper blade kink, caused by contact to the centre screw of the lower windshield reveal moulding, may be found on some 1989 Pontiac Bonneville models.

This condition occurs due to build variations where the wipers park low and the lower reveal moulding is positioned high.

If the wiper is streaking and the blade has a kink caused by parking on the centre screw, perform the following repair procedures.

1. Check the centre screw in the lower reveal moulding. If it is hex head screw, replace it with a flat head cross drive screw, Part Number 11509083. See Illustration.

2. Replace driver's side wiper blade.

3. Operate wipers and verify that screw does not kink blade when wiper is parked.

IMPORTANT: Examine the wiper blade at park, it may park over the screw so long as it does not contact the screw. If contact is apparent, remove and reset the wiper arm so that the blade does not contact the screw.

Use existing Labour Operation to replace wiper blade; includes replacement screw if necessary.
