If your car’s Cd player isn’t working, there are a few things you can try to get it up and running again. One thing to check is that the Cd player is properly plugged into the car’s electrical system. If it’s not, that could be why it’s not working. You can also try cleaning the Cd player’s laser lens with a soft cloth to remove any dirt or debris that may be blocking the laser from reading the Cd. If that doesn’t work, you may need to take the Cd player to a mechanic to have it repaired.
