SUBJECT:
INTERMITTENT DASH BRAKE TELLTALE LIGHT OPERATION
MODELS AFFECTED: 1986-89 RIVIERA, AND 1988-89 REATTA
Some 1986-1989 Riviera and Reatta vehicles may experience a condition of dash brake telltale light staying on, or remains off with parking brake set.
This condition may be caused by a cracked brake switch.
To correct this condition replace the park brake switch with Part Number 3521242.
Parts are currently available from GMSPO.
IMPORTANT:
The old park brake switch has other General Motors applications. Therefore, orders for the original part number switch will not be
superseded by part number 3521242.
