ISSUE:
The front door glass may separate from the glass bracket because of poor adhesive material. A procedure has been developed for refastening the door glass assembly when the bracket separates from the glass. Previously, replacement of the entire glass assembly was required.
ACTION:
Thoroughly clean the glass bracket and reattach it to the glass. Refer to the following procedure for service details.
SERVICE PROCEDURE
Remove the glass assembly from the front door. Refer to the 1990 Thunderbird/Cougar Service Manual or the 1990 Continental Service Manual, Section 42-03, for the removal procedure.
Mark the glass for the bracket location before cleaning it.
Thoroughly remove all pink primer from the plastic bracket.
Soak it in a tray filled with General Purpose Adhesive Cleaner (3M #08984) for about twenty (20) minutes.
Use a wire brush to clean the inside wall of the "U" channel plastic bracket.
Clean glass at the bracket location with the same adhesive cleaner.
NOTE: BE CAREFUL NOT TO REMOVE MARKED LINES FOR THE BRACKET LOCATION WHEN CLEANING GLASS.
Reinstall the front door glass assembly. Refer to the 1990 Thunderbird/Cougar Service Manual or the 1990 Continental Service Manual, Section 42-03, for the installation procedure.
Mix and apply 3M two part adhesive system Structural Adhesive (3M #08101) to the inside wall of the "U" channel plastic bracket.
NOTE: THE MIXED ADHESIVE HAS A FOUR (4) TO FIVE (5)MINUTE DRYING TIME. AFTER FOUR (4) HOURS OF CONTINUED CURING TIME AT ROOM TEMPERATURE, THE BRACKET ADHESION WILL MEET THE FORD SPECIFIED PULL TEST. FULL CURE TIME IS 48 HOURS.
Schedule the glass bracket repair for four (4) hours to accommodate the necessary curing time. Advise the customer to restrict use of the window system for a minimum of 48 hours so that full adhesive cure can take place.
