DISCLAIMER - Some technical knowledge is needed for
the repair of this car stereo. If you do not have the aptitude for repair
or proper tools,
please do not attempt these instructions. We are not responsible for any
damage you may be incurred in the attempted repair of this car stereo. Our
Do It Yourself repair instructions are 99% accurate.
Part number
for lamp 16208443
Use a small common screw driver to release tab on all locks around face of
car stereo by lifting center of tabs up.
One tab, on side of car stereo is a lift of entire tab.
Gently pull face plate from stereo, there is a ribbon cable connected to
front display board. It is important that front face plate is removed
straight off of car stereo frame. When reinstalling face plate, face plate
must be installed straight onto frame of stereo so connection pins are not
bent.
When snapping face plate back into radio, this display lamp circuit board
fits into a slotted attachment to the top of the case of the stereo (Slot
is shown in next picture). Be sure circuit board fits into slot.
Not aligning printed circuit board to notch will result in shorting this
circuit board and burn circuit and components.
With small common screw driver or needle nose pliers twist lamp to
release. In some cases, this lamp is slightly soldered to the circuit
board. Apply pressure to remove lamp.
Install new lamp and assemble.
I have the luxury of a test bench to verify a working display. You will
have to reinstall car stereo into dash to check.

Speakers cut in and out intermittently, treble/bass controls
have static when adjusting.
Adjusting treble/bass slide
controls can cause speakers to go in and out with static.
This is a simple DIY Repair.
Radio Shack sells a "Control Cleaner" with lubricant. Push slide controls
down. Spray into top of slide control opening and move slide control up
and down to clean and lubricate.
NOTE - This model Corvette, 85 to 88 1/2
rarely has a Bose amplifier problem. If cleaning the treble/bass controls
does not take care of speaker problems, see How to
Troubleshoot Your Corvette Bose System.
