Solution

1. Preparation

Gather required tools: socket set, multimeter, flathead screwdriver, and a replacement fuse if necessary.
Ensure the vehicle is parked on a level surface with the ignition off.

2. Check Wiper Control Switch

Sub-step 1: Remove the cover from the steering column using a flathead screwdriver.
Sub-step 2: Disconnect the wiper control switch connector.
Sub-step 3: Use a multimeter to test for continuity when the switch is activated. If faulty, replace the switch.

3. Inspect and Replace Fuse

Sub-step 1: Locate the fuse box, typically found under the dashboard or in the engine compartment.
Sub-step 2: Identify the wiper fuse (refer to the fuse diagram).
Sub-step 3: Remove the fuse with a fuse puller or pliers and inspect for continuity. If blown, replace it with a fuse of the same amperage.

4. Test Wiper Motor

Sub-step 1: Disconnect the wiper motor connector.
Sub-step 2: Connect the motor directly to a 12V power source using jumper wires.
Sub-step 3: If the motor operates, the issue may lie in the wiring or control switch; if it does not, replace the wiper motor.

5. Inspect Wiring and Connectors

Sub-step 1: Visually inspect the wiring harness leading to the wiper motor for any frayed wires or corrosion.
Sub-step 2: Repair any damaged wires or replace connectors as needed.

6. Check Wiper Linkage

Sub-step 1: Remove the wiper arms by loosening the nut at the base.
Sub-step 2: Inspect the wiper linkage for any signs of damage or binding.
Sub-step 3: If damaged, replace the wiper linkage assembly.
