How to Troubleshoot a Cadillac Radioby Alibaster Smith
The radio in your Cadillac should give you years of trouble-free performance. However, you may need to eventually replace it. Replacement radios can be purchased from many different aftermarket suppliers, such as Alpine or Kenwood, or you can purchase replacement radios directly from General Motors.
Remove the fuse panel cover underneath the dash and locate the fuse for the radio. Use the fuse diagram on the underside of the fuse panel cover to locate the radio fuse.
Remove the fuse from the fuse panel using the fuse pullers located in the fuse panel.
Check the fuse for the radio. If the metal strip in the fuse is burned or broken, replace the fuse with another fuse of the same amperage.
Turn the power to the radio on. If the radio won't turn on, the power connector may be unplugged or the wiring may be damaged. You will need to have the wiring replaced or fixed if it is damaged. If the radio does turn on but you get a "CODE" error message, you will need to enter the security code into the keypad on the radio that was given to you by the dealership to unlock the radio so that you can use it.
Check to make sure you can tune the radio and that you are getting good reception. While reception will depend on a variety of factors, if you never seem to get good reception, it may indicate a problem with the antenna plug or the wiring.
