Solution

1. Preparation

Gather the necessary tools: screwdrivers, multimeter, socket set, wrenches.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Inspect and Replace Wiper Control Stalk

Remove the steering column covers using a screwdriver.
Disconnect the wiper control stalk connector.
Inspect the stalk for any visible damage or wear.
If damaged, replace it with a new wiper control stalk.
Reconnect the stalk and reassemble the steering column.

3. Check and Replace Wiper Relay

Locate the fuse panel; refer to the owner's manual for the exact location.
Identify the wiper relay and remove it.
Test the relay with a multimeter to check for continuity (replace if faulty).
Install a new relay if necessary, ensuring it is seated correctly in the fuse panel.

4. Inspect and Repair Wiring

Check the wiring harness from the wiper control stalk to the wiper motor for any signs of damage.
Repair any frayed or damaged wires using electrical tape or by replacing sections of the wiring.
Secure all connections to prevent future issues.

5. Test Wiper Motor

Disconnect the wiper motor connector.
Use a multimeter to check for voltage at the connector while activating the wiper switch.
If no voltage is detected, further inspect wiring or replace the wiper motor if required.
If voltage is present but the motor does not operate, replace the wiper motor.
