My '99 Tahoe is working fine, except for the radio/CD player. It worked
until yesterday and then just quit. It has no sound, but you can read the
station the radio is on and the CD read out is fine....just no sound.
Everything is normal...but no sound. Has anyone had this problem and if so,
what is the fix? Is it a fuse? Is the amplifier gone? I should mention
that it has the SCV feature where the sound of the radio lowers as you slow
down and raises as you go faster to compensate for noise levels.
If there is a short in a speaker wire it would most likely stop all sound
from coming out. Was there anything that would have caused a speaker wire to
break and short?
I have never had a encounter with a SCV radio, but I would assume that if
there is no signal from the SCV sensor that tells the radio the speed (if
that's how it works) that the radio would just work normally.
a shorted speaker will spell the death of the outputs on any factory
amplifier. they tend not to have the solid protection circuits that even
entry level aftermarket amps do.
sounds like the head is toast...a good test would be to swap in a known-good
unit for the original. yours is the one with the cassette/display in the
dash radio location, and the slim cd player unit underneath?
if so, make sure you get the right replacement unit with controls for the cd
player. you can bet the head unit is toast.

Sounds like your amplifier may be shot. Pull the radio and check all the
connections, and all your fuses to be sure. If it is, your only option is to
replace. You may find one in an auto salvage yard, but most likely your best
bet is aftermarket. You don't mention whether or not you have OnStar and
whether or not it's important to you. That's important in the decision
making process since aftermarket head units are more problematic if you use
Assuming you don't use OnStar, you're best bet is going to be the Pioneer
CD-receiver sized at 1 1/2 DIN so it will fit your dash opening exactly.
It's a far better head unit than stock, and looks better. It's about a 15
minute install, complete drop-in with no ugly face plate adapters or
anything like that. $249, includes wiring harness (no solder/splice) and

You may be right about the amp. I checked all the fuses on the fuse block in
the engine compartment and they are all fine, so unless there is a separate
fuse system for the stereo, it's not that. It doesn't have OnStar, so
that's not a factor. I guess the next step is to pull the radio/CD/cassette
and check that. It's a leased vehicle, so I'm not really enthused about
spending money to replace the stereo system. $249 seems reasonable, though.
I will have to ponder that! Thank you for the suggestions!
When installing audio systems in leased vehicles, we insist that we use wire
harness integrator plugs and full dash kits. This allows us to do all our
soldering/taping/messing to a removable harness and simple plug into the
factory wires. The dash kit is the same...simply bolts into the factory
radios place, offering a secure and attractive place for the new radio.
Upon return to the dealer, it is VERY quick to remove the aftermarket stuff
and plug in the old factory radio. In many cases, dealerships NEVER knew
there was a system in the vehicle! And thats the way it should be....now
you can take your investment (in aftermarket car audio) onto the next
vehicle. the only "loss" is that if you get a different vehicle, you'll
need a different plug and plate ($20 cdn each) big deal to preserve
warranty and lease returnability!!!

You are correct about the unit I have. Cassette on top/CD player on the
bottom and radio and controls in the middle with the SCV feature. I still
haven't had the time to get the unit out of the dash to see if a plug came
loose or what. I plan to take it in to a car audio place and have it tested
once I do. We were driving on a very rough road several times while
camping, and while I hope that Chevy's are built tougher than that, I think
something may have jarred loose--at least one can hope that's the problem.
The music died after we got home. If the amp is bad, I will probably not
replace it until I turn it in at lease end. The Tahoe is not my primary
driver so it's not a high priority; the stereo in the other car is fine.
I appreciate all the suggestions and will post again once I figure out what
went wrong so all who are interested and may encounter the same problem will
know. I hope that will be soon. I sometimes work 7 days a week for 3 or 4
weeks at a time and this is one of those times. 2 more weeks and I get a
