However, there's no single guaranteed location. The best approach is to:
1. Consult your owner's manual: This is the most reliable source. It will have a diagram of the underhood fuse box showing the location of all fuses and breakers.
2. Check the underhood fuse box diagram: Even without the manual, there's usually a diagram attached to the inside of the cover of the underhood fuse box.
3. Look for a breaker labeled "Wipers" or something similar: The label might be abbreviated.
If you can't find it using these methods, a qualified mechanic or auto electrician can help you locate and diagnose the problem. Don't attempt to guess which breaker it is – you could damage other components.
