1. Faulty wiring: Check the wiring harness for any damage, corrosion or looseness. Repair or replace any faulty wiring as needed.
2. Overloading of the circuit: Too many accessories or devices may be connected to the same circuit as your wipers. Disconnect non-essential accessories and see if that resolves the problem.
3. Worn-out wiper motor: A worn-out wiper motor can draw more current than normal and cause the fuse to blow. Replace the wiper motor if it is found to be faulty.
4. Shorted wiper switch: A shorted wiper switch can cause the wipers to run continuously and draw too much current, leading to blown fuses. Replace the wiper switch if it is found to be faulty.
5. Bad ground: Check the ground connections for the wiper circuit to ensure that they are clean and tight. Clean or repair any faulty ground connections.
If you are uncomfortable performing these checks or repairs yourself, it is best to take your vehicle to a qualified mechanic for diagnosis and repair.
