Solution

1. Preparation

Gather tools and materials: OBD-II scanner, multimeter, socket set, replacement fuses/relay (if needed).
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Check and Replace Fuses

Locate the fuse box: Refer to the owner’s manual for the exact location of the fuse box.
Remove the cover and inspect the wiper fuse (typically labeled as "Wiper" or "WIPERS").
Test the fuse: If blown, remove it using fuse puller or pliers.
Replace the fuse: Insert a new fuse of the same amperage (usually 10A or 15A).

3. Inspect and Replace Relay

Locate the wiper relay: Find it in the relay box, usually near the fuse box.
Remove the relay: Pull it straight out using your fingers or a relay removal tool.
Test the relay: Use a multimeter to check for continuity. If defective, replace with a new relay.

4. Test and Replace Wiper Motor

Locate the wiper motor: It is typically found under the cowl panel at the base of the windshield.
Disconnect the motor connector: Ensure the ignition is off.
Test for power: Use a multimeter to check for voltage at the motor connector when the wiper switch is activated.
Replace the motor: If no power is detected, replace the motor. If power is present but the motor doesn’t function, replace the motor.
- Removal: Unbolt the motor from the mounting bracket.
- Installation: Position the new motor and secure it with bolts, ensuring proper alignment with the wiper linkage.

5. Reconnect Battery and Test Wipers

Reconnect the negative battery terminal.
Turn on the wipers to verify functionality.
