C4 BOSE WOES: Repairing & Replacing 84-96 Bose Speakers & Amps

lead shot

If you own a C-4 equipped with Bose sound system, you will eventually need Bose amplifier repair or replacement. Every Bose sound system equipped C-4 uses one amplifier per speaker. This is the weak link. Amplifier capacitors are filled with electrolytic fluid which ultimately leaks out onto the circuit board causing failure. If the leak is slow, the amplifier’s circuit board can be damaged beyond repair. Electrolytic fluid is acidic and will corrode anything it touches.

Introducing Correct C1 Push-Down Antennas from Corvette Central

Corvette Central is pleased to introduce correct push-down antennas for C1 Corvettes, available in three versions: 1956-58 (early), 1958 (late)-60 and 1961-62.  Our new assemblies not only reflect the attention to detail that judges are looking for during shows, but our dedication to producing the highest quality parts possible.  As an example, the antenna tips on all three versions of our C1 antennas are identical to factory specifications.

161021 (1956-1958E)
Correct push down mast antenna as original. No rings on mast.  Fully extended, the mast is 45 inches. Normal height, not extended, is 11.5 inches. The mast pushes down into the antenna approximately 2 inches as they did from the factory.

161017 (1958L-1960)
Correct push down mast antenna as original. Features rings on mast.  Fully extended, the mast is 45 inches. Normal height, not extended, is 11.5 inches. The mast pushes down into the antenna approximately 2 inches as they did from the factory.

C4 Diagnostic Trouble Codes

By Chris Petris

Codes, Codes, Codes…

Have you noticed “SYS” intermittently showing up in your 1990-1996 Corvette’s speedometer display?  This means there is a trouble code stored in one of the on-board control modules.  When the 1990 Corvette debuted, GM introduced ECM (Engine Control Module) and CCM (Central Control Module) trouble codes.   In addition, ABS/ASR (Anti-lock Brake System/Acceleration Slip Regulation) and EBTCM (Electronic Brake Traction Control Module) trouble codes and data were introduced on the 1992-1996 Corvettes.  Although limited ECM data is available, it can point you in the right direction.  For example, the CCM interaction is invaluable when diagnosing interior component or courtesy light problems and the VATS (Vehicle Anti-theft System).  The ALDL (Assembly Line Diagnostic Link) is used to access the codes with a jumper wire.  The jumper wire is placed in the proper connector slots and the interrogation begins.  Interrogation can be a daunting task.
