Subject:
CENTER HIGH MOUNTED STOP LAMP CONTACTS REAR WINDOW
Model and Year:
1991 BERETTA
Condition:
Owners of some 1991 Beretta models may comment on a rattling noise coming from the Center High Mounted Stop Lamps (CHMSL)
when experiencing rough road conditions.
Cause:
The CHMSL loosens from the support because the current CHMSL mounting screws cannot be tightened enough to provide the proper
clamping load without stripping. The rattling noise is caused by a vibration that originates from the rear wheels and is transmitted to the
rear shelf panel. This vibration causes the loose CHMSL to contact the rear window and create the noise.
Correction:
Replace current CHMSL 4.2 mm mounting screws with new 4.8 mm screws, P/N 11505446. Position CHMSL fully forward on the
support before inserting and tightening new mounting screws. Tighten screws securely without stripping.
Parts are currently available from GMSPO.
