If the volume knob of the car radio and the CD player do not work, there is an electronic issue inside the car radio: to perform this repair, you need to be familiar with electronic repairs and have the appropriate tools, as you will need to replace a driver on the car radio's circuit board.

Start by removing the car radio from the console using the appropriate removal tools, disconnect the connectors, and disassemble the car radio to access the circuit board.

The driver to be replaced is located under the metal plate.
