Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Disconnect the battery to prevent electrical shock or short circuits.

2. Inspect and Replace the Wiper Fuse

Tools Required: Fuse puller or 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 cover.
Pull the fuse and inspect it for continuity. Replace with the same amperage fuse if blown.

3. Test and Replace the Wiper Motor

Tools Required: Multimeter, socket set
Reconnect the battery and turn on the wiper switch.
Use a multimeter to test for voltage at the wiper motor connector.
If no voltage is present, the issue may lie with the switch or wiring.
If voltage is present, remove the wiper motor using a socket set.
Replace the motor if it fails the bench test (no movement when powered directly).

4. Inspect and Repair Wiring

Tools Required: Wire strippers, electrical tape, connectors
Visually inspect the wiring harness for damage or corrosion.
Repair any broken or frayed wires using proper connectors.
Use electrical tape to insulate any exposed wires.

5. Check the Wiper Linkage

Tools Required: Socket set, lubricant
Remove the wiper arms and the plastic cover from the wiper motor assembly.
Inspect the linkage for wear or damage.
Lubricate any moving parts and ensure all connections are tight.
Replace any damaged components as necessary.
