Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery to prevent electrical shorts.

2. Replace Wiper Fuse

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.
Remove the fuse using a fuse puller or needle-nose pliers.
Inspect the fuse for continuity; replace it with a new one of the same amperage if blown.

3. Test and Replace Wiper Motor (If Necessary)

Reconnect the battery and activate the wiper switch.
Using a multimeter, check for voltage at the wiper motor connector.
If power is present but the motor does not operate, remove the wiper arms by loosening the securing nuts with a socket set.
Unscrew the motor assembly from its mounting bracket and disconnect the wiring harness.
Install the new wiper motor by reversing the removal steps and ensuring all connections are secure.

4. Inspect and Repair Wiper Linkage (If Necessary)

If the motor is functioning but the wipers are not moving, inspect the linkage.
Remove any covers to access the wiper linkage assembly.
Check for wear, breaks, or disconnections in the linkage.
Replace any damaged parts and lubricate the linkage components.

5. Test Wiper Functionality

Reconnect the battery and test the wiper operation by cycling through all speed settings.
Ensure the washer pump is also functional by activating the washer switch and checking for fluid spray.
