Door Glass (Front/Rear) - Guide Pin Clip Installation

Bulletin: 91-10-29

Date: August 91

Ref. No.: 91-235-10

Corp. Ref. No.: 131033


SUBJECT:
PLIABILITY OF FRONT AND REAR DOOR GLASS GUIDE PIN CLIPS
(PRE-SOAK GUIDE PINS)

MODELS AFFECTED:
1989-91 SKYLARKS


CONDITION:
Service technicians are having problems securing guide pin clips to front and rear door windows, resulting in damage to the clips in many cases.

CAUSE:
The clips are shipped in bulk quantities to the plant and to GMSPO wet-packed. However, GMSPO has the clips re-packaged, and they are not wet-packed when stored at GMSPO or when shipped to the dealers.

CORRECTION:
Service technicians must pre-soak the door glass guide pins for eight hours in a container of water prior to installation. Or
Suggest that dealers re-package the clip into a Zip-Loc (R) bag partly filled with water as soon as they are received in the parts department.

Pre-soaking of the guide pin allows the guides to become more pliable thus enhancing the capability of fully securing the guide to the window. When the guide is being installed, an audible "snapping" sound should be heard, which indicates that the guide is fully seated.
