Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and screwdriver.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Replace Blown Fuse

Sub-steps:
1. Locate the fuse box (typically under the dashboard or in the engine compartment).
2. Remove the fuse cover and locate the wiper fuse (refer to the fuse diagram).
3. Use a fuse puller or pliers to remove the fuse.
4. Inspect the fuse for a broken filament. If broken, replace it with a fuse of the same amperage (usually 10A or 15A).

3. Repair or Replace Wiper Motor

Sub-steps:
1. If the motor is found faulty during testing, disconnect the electrical connectors from the motor.
2. Remove the wiper arms by loosening the retaining nuts, then gently lift them off the splines.
3. Unscrew the mounting bolts securing the wiper motor to the vehicle.
4. Remove the motor from its bracket and replace it with a new or tested working motor.
5. Reassemble by reversing the disassembly steps, ensuring all connections are secure.

4. Inspect and Repair Wiper Linkage

Sub-steps:
1. Remove any obstructions that may prevent the wiper linkage from moving freely.
2. Check the linkage for any broken or disconnected parts and replace them if necessary.
3. Apply lubrication to the joints of the linkage to ensure smooth operation.
