To find it, you'll need to:
1. Consult your owner's manual: This is the most reliable source. The manual will show you diagrams of both fuse boxes and clearly indicate which fuse controls the power mirrors.
2. Check the fuse box labels: Once you've located both fuse boxes, carefully examine the labels on the fuse covers or the fuse box itself. Look for labels that mention "power mirrors," "side mirrors," "exterior mirrors," or similar terms.
3. Look for a fuse of the appropriate amperage: The amperage will also be listed in the owner's manual.
Important Note: If you're not comfortable working with electrical systems, it's best to consult a qualified mechanic. Improperly handling fuses can damage your vehicle's electrical system.
