If your car radio got wet, there are a few things you can do to fix it. First, unplug the car radio and wait 10 minutes for the power to dissipate. If the power is still present, then you will need to remove the battery. Next, remove the cover of the car radio and locate the motherboard. There are usually two screws that hold it in place. Once those screws are removed, gently pull out the motherboard. If water got inside of the car radio while it was plugged in, you will need to clean all of the components with a dry cloth or vacuum cleaner. Once everything is clean, replace the motherboard and screw it back in place. Finally, plug in your car radio and test it out! ..
