Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, replacement fuses/relay (if necessary).
Ensure the vehicle is parked on a flat surface and the ignition is off.

2. Inspect and Replace Wiper Control Stalk

Sub-steps:
1. Remove the steering column cover using a socket set (typically requires T20 or T25 screws).
2. Disconnect the wiper control stalk connector from the wiring harness.
3. Test the stalk with a multimeter to ensure it functions correctly according to specifications (check for continuity).
4. If faulty, replace the wiper control stalk with a new one, ensuring all connections are secure.

3. Check and Replace Fuses

Sub-steps:
1. Locate the fuse box (usually under the dashboard or in the engine compartment).
2. Identify the wiper fuse (refer to the fuse diagram).
3. Remove the fuse and inspect for continuity using a multimeter.
4. If blown, replace it with a fuse of the same amperage rating.

4. Inspect and Replace Wiper Relay

Sub-steps:
1. Locate the relay box (generally near the fuse box).
2. Identify the wiper relay (consult the owner's manual for the correct location).
3. Remove the relay and test it by swapping with a similar relay from a non-essential circuit.
4. Replace with a new relay if the wipers function correctly with the swapped relay.

5. Reassemble and Test

Sub-steps:
1. Reattach the steering column cover and ensure all screws are tightened.
2. Turn on the ignition and test the wiper function in all modes.
3. Confirm that the wipers turn off when the switch is returned to the off position.
