1. Locate Fuse 13: Fuse 13 is responsible for the radio and cigarette lighter in your Mercedes 190E. It is located in the fuse box, which is usually found under the hood of your car, near the battery. Consult your vehicle's owner manual for the exact location of the fuse box.
2. Check the Fuse: Carefully remove fuse 13 from the fuse box. Visually inspect the fuse to see if it is blown. A blown fuse will typically have a broken filament or a darkened appearance. If fuse 13 is not visibly damaged, you may need to test it with a multimeter to confirm that it is still functioning.
3. Replace the Fuse: If Fuse 13 is blown or faulty, you will need to replace it with a new fuse of the same amperage rating. Be sure to use the correct type of fuse specified in your vehicle's owner manual. Never replace a fuse with one of a higher amperage rating, as this can lead to electrical issues or even a fire.
4. Check for Underlying Issues: Once you have replaced fuse 13, turn on the radio and test the lighter to see if they are working again. If the issue persists, there may be an underlying electrical problem that requires further diagnosis. This may involve checking the wiring for any breaks, shorts, or loose connections, as well as inspecting the radio and lighter themselves for any internal issues.
5. Seek Professional Help: If you are uncomfortable performing electrical work or if you are unable to identify and fix the problem, it is recommended to seek assistance from a qualified mechanic or auto electrician. They have the necessary expertise and equipment to diagnose and resolve electrical issues in your vehicle safely and efficiently.
