File In Section: 10 - Body
Bulletin No. 53-15-05
Date: March, 1995

Subject:
Rear Compartment Lid "Boom" Sound When Lid is Opened (Adjust Rear Bumpers, Latch, and/or Pull-down Unit)

Models:
1994 Cadillac Concours, DeVille

CONDITION
Some owners may comment on a "boom" sound when the rear compartment lid is opened.

CAUSE
Excessive load between the lid pull-down unit and latch assembly is deflecting the lid inner panel. As the lid is opened, energy is released from the inner panel, resulting in a "boom" sound.

CORRECTION

1. Adjust two (2) rear bumpers all the way up.
2. Reset flushness of lid to quarter panels by adjusting the latch and/or the lid pull-down unit.
3. Reset rear bumpers to set up/down flushness to quarter panels without exerting excess force to the pull-down unit.
