Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Wiper Relay

Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the wiper relay (refer to the fuse box diagram).
Remove the relay and test it using a multimeter for continuity.
If faulty, replace the relay with a new one.

3. Check and Repair Electrical Connections

Inspect the wiper motor connector for corrosion or loose connections.
Clean the terminals with electrical contact cleaner.
If any wires are frayed or damaged, repair or replace them as necessary.

4. Test and Replace Wiper Motor (if needed)

Reconnect the battery and turn the wipers on to see if they operate.
If the wipers do not function, remove the wiper motor from its mount.
- Disconnect the motor's electrical connector.
- Remove the mounting bolts (usually 10mm) and lift the motor out.
Install a new wiper motor by reversing the removal steps.

5. Reassemble and Test

Ensure all connections are tight and components are secure.
Reattach the wiper arms if removed and ensure they are positioned correctly.
Test the wiper operation through all speeds and functions.
