- A defective wiper motor can draw excessive current, causing the fuse to blow.
2. Wiring Issues:
- Short circuits or damaged wiring in the wiper circuit can overload the fuse.
3. Wiper Linkage Mechanism:
- Worn-out or jammed wiper linkage parts can put extra strain on the motor, leading to fuse damage.
4. Faulty Wiper Switch:
- A malfunctioning wiper switch can send incorrect signals, overloading the fuse.
5. Overloaded Fuse:
- Check the rating of the wiper fuse; if it's lower than recommended, upgrade it to the correct amperage.
6. Water Leakage:
- If water has reached the wiper motor wiring or switch, it can cause shorts and blow the fuse.
7. Wiper Relay Issues:
- A faulty wiper relay, if present, can cause fuse failures.
8. Aftermarket Components:
- Non-genuine or incorrectly installed components may cause compatibility problems.
To pinpoint the actual cause, further inspection and testing by a qualified mechanic or electrician is crucial.
