Solution

1. Preparation

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

2. Remove Wiper Control Stalk

Use a Torx screwdriver to remove the steering column cover.
Disconnect the battery (if not already done).
Remove the screws holding the control stalk in place.
Carefully pull out the control stalk and disconnect the wiring harness.

3. Inspect and Test

Visually inspect the wiper control stalk for damaged components.
If necessary, use a multimeter to test the continuity of the stalk's circuits.
If defective, replace with a new control stalk.

4. Check Wiper Relay

Locate the wiper relay in the fuse box.
Remove the relay and inspect for damage.
Test the relay by applying voltage to the terminals as per manufacturer specifications.
Replace the relay if it does not operate correctly.

5. Reinstall Components

Reconnect the wiring harness to the new or repaired control stalk.
Position the control stalk back into the steering column and secure with screws.
Reattach the steering column cover.

6. Finalize Setup

Reconnect the vehicle battery.
Test the wipers for proper intermittent function and adjust settings as necessary.
