Subject: REAR WINDOW DEFOGGER GRID LINES OPEN


Model and Year: 1990 W CAR
Owners of a few 1990 Lumina coupes/sedans equipped with rear window grid defoggers may comment that some grid lines are not functioning.

Non functioning grid lines may be caused by the CHMSL seal contacting the glass and rubbing through the grid lines.

Determine which grid lines need repair by first removing the CHMSL shade and seal assembly. Reference the stationary glass section of the Body Service Manual for complete grid line repair procedure. Part Number for repair kit has been changed to 12345345.

Part is currently available from GMSPO.

After repair of grid lines, position shade and seal assembly in place and note areas where seal contacts grid lines. Remove enough material from the seal to prevent seal contacting glass.
