To find the correct fuse size:
1. Consult your owner's manual: This is the best source. It will have a fuse diagram showing the amperage rating for each fuse in your vehicle, including the one for the washer pump.
2. Check the fuse box diagrams: There are usually diagrams on the inside of the fuse box covers themselves. This will show the fuse locations and ratings.
3. Look at the blown fuse (if applicable): If the washer pump isn't working and you suspect a blown fuse, the amperage rating will be printed on the blown fuse itself.
Important Note: Never replace a fuse with one of a higher amperage rating. Using a higher-amperage fuse could damage the wiring or even cause a fire. If a fuse keeps blowing, there's likely a short circuit somewhere in the system that needs to be repaired by a qualified mechanic.
