- A short circuit in the wiring. This is the most likely cause, and it can be caused by a number of things, such as a damaged wire, a loose connection, or a faulty switch.
- A faulty windscreen wiper motor. If the motor is drawing too much current, it can cause the fuse to blow.
- A problem with the wiper linkage. If the linkage is binding or damaged, it can put extra strain on the motor, causing it to draw too much current and blow the fuse.
To troubleshoot the problem, you will need to:
1. Check the wiring for any damage or loose connections. If you find any damage, repair it or replace the wiring as needed.
2. Test the windscreen wiper motor. You can do this by connecting the motor directly to the battery. If the motor runs, it is good. If it does not run, replace the motor.
3. Check the wiper linkage for any binding or damage. If you find any problems, repair or replace the linkage as needed.
Once you have repaired or replaced the faulty parts, the windscreen wiper fuse should stop blowing.
