Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to ensure safety during repairs.
Ensure the vehicle is parked on a flat surface and the ignition is off.

2. Inspect and Replace Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Remove the fuse box cover and locate the wiper fuse (refer to the owner's manual for the correct fuse location and rating).
Inspect the fuse for any signs of damage (broken filament).
If damaged, replace it with a new fuse of the same rating.

3. Test and Replace Wiper Motor

Locate the wiper motor, usually found beneath the cowl panel at the base of the windshield.
Disconnect the wiring harness from the motor.
Using jumper wires, connect the motor directly to the battery (positive and negative).
If the motor operates, it may need reinstallation; if not, replace with a new motor.
To replace, remove any mounting bolts, disconnect the wiper linkage, and install the new motor in reverse order.

4. Reassemble and Test

Reattach any covers or panels removed during the process.
Reconnect the battery.
Test the wipers in all settings to ensure proper function.
