Solution

1. Preparation

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

2. Inspect and Replace Fuse

Tools Required: Fuse puller or needle-nose pliers
Locate the fuse box (typically under the dashboard or in the front trunk).
Identify the fuse related to the windshield wipers (refer to the owner's manual for the specific fuse location).
Remove the fuse and inspect it; if blown, replace it with a new fuse of the same amperage.

3. Test the Wiper Motor

Tools Required: Multimeter, jumper wires
Locate the wiper motor (usually under the hood).
Disconnect the wiper motor connector.
Use a multimeter to check for voltage at the connector while the wiper control stalk is activated.
If voltage is present, connect the jumper wires directly to the motor terminals to check for operation. If the motor does not work, it may need replacement.

4. Inspect Wiper Linkage

Tools Required: Socket set, screwdriver
Remove the wiper arms by loosening the retaining nuts and carefully pulling them off.
Inspect the linkage mechanism for any signs of wear, disconnection, or damage.
If damaged, replace the wiper linkage assembly.

5. Reassemble and Test

Reinstall the wiper arms securely.
Reconnect the battery.
Test the wipers by activating the control stalk in all settings to confirm proper operation.
