Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the vehicle's battery to avoid electrical shock.

2. Inspect and Replace the Fuse

Tools Required: Fuse puller or needle-nose pliers
Locate the fuse box, typically under the dashboard or in the engine compartment.
Identify the wiper fuse using the diagram on the fuse box lid.
Use the fuse puller to remove the wiper fuse and inspect it for signs of a blown filament.
Replace the fuse with a new one of the same amperage (usually 20A).

3. Test the Wiper Motor

Tools Required: Multimeter, jumper wires
Reconnect the battery temporarily.
Disconnect the wiper motor connector.
Use a multimeter to check for voltage at the motor connector while activating the wiper switch.
If voltage is present, the motor may need replacement. If voltage is absent, proceed to check the relay.

4. Check and Replace the Wiper Relay

Tools Required: None
Locate the wiper relay in the fuse box.
Remove the relay and inspect it for damage.
Swap it with a similar relay to test functionality. If the wipers work with the swapped relay, replace the faulty relay.

5. Inspect Wiring and Connectors

Tools Required: Visual inspection tools
Examine all wires and connectors leading to the wiper motor for signs of damage, corrosion, or loose connections.
Repair or replace any damaged wiring or connectors as necessary.
