Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to ensure safety during repairs.
Tools Required: Wrench set, multimeter, OBD-II scanner, fuse puller.

2. Inspect and Replace the Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify the wiper fuse (refer to the vehicle’s manual for the correct fuse location).
Use a fuse puller to remove the wiper motor fuse.
Inspect the fuse for any signs of damage; replace if blown.
Reinstall the fuse and reconnect the battery.

3. Test the Wiper Motor

Disconnect the wiper motor connector to access the terminals.
Using a multimeter, check for voltage at the motor connector while the wiper switch is activated.
- If voltage is present, proceed to the next step.
- If no voltage, check the wiring and switch.
If voltage is present, apply direct power to the motor terminals to test its functionality.
If the motor does not run, it may require replacement.

4. Check the Wiper Linkage

Remove the wiper arms by loosening the nuts at their bases using a socket set.
Carefully lift the wiper arms off the splines.
Inspect the wiper linkage for any signs of damage or disconnection.
If damaged, replace the wiper linkage assembly.
