Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the negative battery terminal to ensure safety.
Tools Required: Socket set, multimeter, wire brush, electrical tape.

2. Inspect and Replace the Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify the wiper fuse using the diagram on the fuse box cover.
Remove the wiper fuse and inspect it for any signs of damage or a blown element.
If the fuse is blown, replace it with a new fuse of the same amperage.

3. Test and Replace the Wiper Motor

After confirming the fuse is functional, reconnect the negative battery terminal.
Activate the wipers; if there is no movement, proceed to test the wiper motor.
Disconnect the wiper motor connector and use a multimeter to check for voltage when the wiper switch is activated.
If no voltage is present, trace the wiring back to the switch for faults.
If voltage is present but the motor does not operate, replace the wiper motor.

4. Inspect Wiper Linkage

If the motor is functional, remove the wiper arms by unscrewing the retaining nuts.
Take off the cover to access the wiper linkage.
Inspect the linkage for any signs of wear or disconnection.
If damaged, replace the wiper linkage assembly.
