Understanding the 2012 Volkswagen CC Fuse Box Diagram
The fuse box acts as the electrical nerve center of your car, protecting individual circuits from electrical overloads. The 2012 Volkswagen CC features two main fuse boxes: one located in the engine compartment and the other inside the passenger compartment.
The engine compartment fuse box, often referred to as the “underhood fuse box,” is a robust black box, typically found on the driver’s side. It houses the majority of fuses for essential components like the headlights, engine, and cooling system. This is where you’ll encounter the larger fuses, usually rated in amps (A).
The passenger compartment fuse box, often located under the dashboard on the driver’s side, is usually smaller and holds fuses for elements like the radio, power windows, and interior lights. While smaller in size, it’s equally important as its counterpart in the engine compartment. This fuse box usually contains fuses rated in milliamps (mA).

The culprit is usually a blown fuse in the passenger compartment fuse box. Refer to the diagram to find the fuse responsible for the radio or audio system and replace it if necessary.
4. Power Windows Not Working:
Check the fuses related to the power windows in the passenger compartment fuse box. Replace any blown fuses with the correct amperage. If the issue persists, there might be a fault in the window motor or wiring.
5. Interior Lights Not Functioning:
Look for the fuse dedicated to the interior lights in the passenger compartment fuse box. Replace any blown fuses to restore functionality.
