Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to prevent electrical shock or shorting.
Ensure the vehicle is parked on a flat surface and the ignition is off.

2. Inspect and Replace Fuses

Locate the fuse box using the vehicle manual.
Remove the cover and identify the fuse for the wipers.
Use a multimeter to check the continuity of the fuse; replace if blown.
Reinstall the fuse box cover.

3. Replace Wiper Relay

Locate the wiper relay in the fuse box or relay panel.
Remove the relay by gently pulling it out.
Install a new relay of the same type and rating.
Reconnect the battery and test the wipers.

4. Inspect and Repair Wiring

Visually inspect the wiring harness connected to the wiper motor and control stalk.
Look for any frayed wires, corrosion, or loose connections.
Repair or replace damaged wires as necessary.

5. Test Wiper Motor Functionality

Disconnect the wiper motor connector.
Use a multimeter to check for voltage at the connector while activating the wiper switch.
If voltage is present but the motor does not operate, replace the wiper motor.
