Can you help me with my radio? I have a 1999 Monte Carlo Z34 with
about 3 blown bulbs. How do you change these bulbs and/or remove the
radio?

I'll assume there is no easy way to accomplish this, but since you
work on these all the time, maybe you can help.



Peter,

The bulbs are soldered to the board, if you are equipped to deal with
soldering on a smallish scale read on:

I don't work at a Chevy garage, so this removal procedure may be a
little vague, but in a nutshell you have to pull the bezel/trim panel
off that goes around the instrument cluster, radio and heater
controls.
Usually these panels are just held in place by spring clips and the
panel should pull straight off. On some applications the bottom of
the panel tucks in under the panel below the steering column. Once
you get the panel off, there will be two or three screws holding the
radio in, after removing the screws the radio pulls straight out.

Remove any round knobs from the front of the radio by pulling straight
off. Pop the top and bottom covers off the radio. find two or three
groups of wires (depending on radio model) coming out from the
faceplate area and plugging into the boards inside the radio, unplug
these wires at the connectors on the boards. Carefully release the
tabs around the perimeter of the faceplate and pull the faceplate
straight off. Looking at the backside of the faceplate you should see
a number of screws holding the display and button circuit board to the
backside of the faceplate. Remove these screws while holding the
board in place. Put the faceplate face down (this is so all the
buttons and light tubes don't fall out of it) and remove the circuit
board.

Now you should be looking at all the lamps! If you have more than a
couple blown, you might want to replace them all while you are there.

Good luck!

Thanks! I have the stuff to solder tiny components, so I should be all
set. If I get the time, I'll try this procedure.

Will the bulb numbers be on the bulbs so I know what to replace them
with? I deleted the previous message(s) with the bulb numbers and where
to order them because I wasn't sure if they applied to my brand or not.

Also, they are incendecent, correct? Another words - no polarity.

It's a silly question, but figured I'd ask it just in case.

Thanks again!
