Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and turn off the ignition.
Disconnect the negative battery cable to ensure safety.

2. Inspect and Replace the Wiper Fuse

Tools Required: Fuse puller or needle-nose pliers
Locate the fuse box (typically under the dashboard or in the engine compartment).
Remove the cover and locate the windshield wiper fuse.
Check the fuse for continuity; replace it if blown with the same amperage.

3. Test and Replace the Wiper Motor

Tools Required: Multimeter, socket set
Reconnect the battery temporarily and activate the wipers.
Use a multimeter to check for voltage at the wiper motor connector while the wipers are activated.
If no voltage is present, further investigate the wiring or switch.
If voltage is present but the motor does not operate, remove the wiper motor (usually involves removing retaining bolts and disconnecting the electrical connector).
Replace the wiper motor with a new one if defective.

4. Inspect and Repair Wiper Linkage

Tools Required: Socket set, possibly pliers
With the wiper motor removed, inspect the wiper linkage for any signs of damage or disconnection.
Reattach or replace any broken parts as necessary.
Reassemble by reversing the disassembly process.
