To find the correct fuse, you need to:
1. Consult your owner's manual: This is the most reliable source. The manual will have a fuse box diagram showing which fuse controls what circuit. Look for a fuse related to "interior lights," "courtesy lamps," or something similar.
2. Check the underhood fuse box diagram: Even without the manual, the underhood fuse box usually has a diagram printed on its inside cover, identifying each fuse.
3. Use a test light: If you can't find the correct fuse using the diagram, you can use a test light to check each fuse in the suspected circuits.
Important Note: Before checking any fuses, make sure the vehicle's ignition is OFF. Working with car electrical systems requires caution.
