CRACKING AT BOTTOM OF WINDSHIELD
Revision: Parts listing expanded; production change information added.
Cracks at the bottom of the windshield may be caused by excessive pressure placed on the glass (b, Figure 1) by the lower trim pieces (d) as their screws
(Figure 2) are tightened. This pressure can lead to stress cracks starting at the bottom of the windshield.
First rubber, then plastic, washers were placed under the trim mounting sleeves in production to ensure adequate clearance to the glass. To eliminate the
need for spacers in most cases, the trim piece was then modified by increasing the length of the sleeves. These production changes occurred on the
following approximate dates.
Effective Production Change Date:
Modification
Production Date
Rubber washers
March 1,1993
Plastic washers
April 26,1993
Longer sleeves
May 17,1993
When installing the trim pieces, make certain to maintain a gap (a, Figure 1) between the trim pieces and the glass by using a piece of paper as a gauge.
If necessary, place 2 mm thick rubber or plastic washers under the trim piece mounting sleeves (d) to raise the trim piece off the glass.
