Chevrolet z71: what could be wrong with a 93 chevy 1500 radio

This answer was rated:

what could be wrong with a 93 chevy 1500 radio evry thing works no sound i changed the radio tuner and the radio box 2 still no sound

 

 

i have changed the radio tuner and radiobox that under the dash stil no sound all buttons work no sound

 

You did not mention if you changed with New, Rebuilt or Used..........

The Tuner / AMP Box is known to have problems & typically you would need to purchase a Rebuilt.
Be sure the one you installed is "exactly" the same Model Number as what came out (if it is stock)
You should Test Speakers by connecting jumper wires from a AAA or 9 Volt Battery & "breifly" touching the Positive & Negative wires of the Unplugged Unit Plug

Wires at plug are:


Constant 12V+ Orange
Switched 12V+ Yellow
Ground Black
Illumination Gray
Front Speakers;
Left Front (+) Tan
Left Front (-) Gray
Right Front (+) Light Green
Right Front (-) Dark Green
Rear Speakers ;
Left Rear (+) Brown
Left Rear (-) Yellow
Right Rear (+) Dark Blue
Right Rear (-) Light Blue

i got the parts at a local junk yard still didnt work thought they may have been bad so i got on ebay got the same parts still did not fix it all the buttons work you can put a casset tape it plays the tape plays but no sonnd its like theres no speakers i dont think all 4 would be bad what do you think it could be

 

There were 3 different models, with & without Cassette, with Cassette & Equalizer & with 4 way fader

It is important that you are sure the correct Unit is installed with the Head Unit up top.
The Head Unit up top is just a Keyboard.

 

i dont think all 4 would be bad what do you think it could be

 

sorry, not correct, as I have seen "4" bad many times.
This is a 1993 & paper cone speakers (if there are 4) do go bad

This is why I gave you wire colors to "pop" the speakers with a AAA or 9 Volt Battery to see if there is any sound.
Be sure Plugs are disconnected from Unit

Also be sure to check Voltage on the ORANGE & YELLOW wires with Key On
You should hear a distinct "click" in the lower Box, when the Unit is turned On
