It can be frustrating when your vehicle keeps blowing the windshield wiper and windshield wiper fuses. There are several reasons for a blown windshield wiper and washer fuse.
Current: wiper fuse
The windshield wiper or washer motor could be drawing too much current. To see if this is the problem, disconnect the windshield wiper motor for a moment. If the fuse does not blow, the motor is drawing too much current.
Interference: wiper fuse
Another reason a blown fuse for the windshield wipers and washers may be a build-up of debris or ice around the windshield wipers. Look around the windshield wipers and see if there is anything that may be interfering with the movement of the arm and remove it. Test to see if this was causing the problem.
Warning: Windshield Wiper Fuse
If you have a fuse that blows continuously, do not replace it with a larger, higher amperage fuse. The fuse size is predetermined to help protect the circuit. Placing a higher amperage fuse where it is not needed will not stop current flow when needed.
