Heated Glass Element: Technical Service Bulletins
Defogger - Rear Window Electric Grid Lines Vary

Bulletin Number:

89-10-38

Reference Number:

981502R

Publish Date:

12/89

Subject:

REAR WINDOW DEFOGGER GRID LINE VARIATIONS

Models

Affected:

1988-89 LEMANS

The rear window electric grid lines vary in thickness as they run from side to side. Design intent is to evenly distribute electrical current over the entire
glass surface.

This does not affect or reduce the performance of the rear window defogger.

When repairing a broken grid, the repair should be the same thickness as the grid line at the point of repair.
