Here are a few possible reasons why the radio buttons might stay lit:
1. Faulty Ignition Switch: If the ignition switch is faulty, it may not properly turn off the electrical power to the radio when the key is removed. This can cause the radio to remain powered and the buttons to stay lit.
2. Wiring Issue: There may be a wiring issue in the car's electrical system that is causing the radio to receive power even when the ignition is off. This could be due to a damaged or loose wire.
3. Radio Malfunction: The radio itself could be malfunctioning, causing it to stay powered even when it should be off.
To resolve this issue, you should take your car to a qualified mechanic or auto electrician to diagnose the exact cause of the problem and have it repaired. They will be able to check the ignition switch, wiring, and radio to determine where the fault lies and perform the necessary repairs to fix it.
In the meantime, to avoid draining your battery, you can try disconnecting the negative terminal of the car battery when the car is not in use. This will prevent any power from being supplied to the radio and other electrical components.
