Solution

1. Preparation

Gather tools: socket set, multimeter, screwdrivers, and replacement parts if necessary.
Disconnect the vehicle battery to eliminate any power to the wiper system.

2. Inspect and Replace Fuse

Locate the fuse box (usually within the glove compartment or under the dashboard).
Remove the fuse for the windshield wipers using a fuse puller.
Inspect the fuse for continuity; replace if blown with a new fuse of the same amperage.

3. Check Wiper Motor

Locate the wiper motor (usually under the cowl panel at the base of the windshield).
Disconnect the electrical connector from the wiper motor.
Use a multimeter to check for voltage at the connector while the wiper switch is on.
If no voltage is detected, trace back to the wiper switch and wiring for issues.
If voltage is present, connect the motor to a direct power source to test its operation.

4. Inspect Wiper Linkage

Remove the wiper arms by loosening the nuts at the base (use a socket wrench).
Carefully lift the wiper arms off the splines.
Inspect the linkage for any broken components or disconnections.
Replace or repair any damaged parts as necessary.

5. Reassemble and Test

Reattach the wiper arms and secure them with nuts.
Reconnect the battery.
Test the wipers in all settings to ensure proper functioning.
