Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.

2. Check and Replace Fuse

Locate the fuse box; refer to the owner's manual for the exact location.
Remove the wiper fuse and inspect it for a break in the filament.
If the fuse is blown, replace it with a new fuse of the same amperage (usually 15A).

3. Inspect and Replace the Wiper Switch

Remove the steering column cover to access the wiper switch.
Disconnect the wiring harness from the wiper switch.
Using a multimeter, test for continuity across the switch terminals.
If the switch is faulty, replace it with a new one, reconnecting the wiring harness securely.

4. Test and Replace Wiper Motor

Locate the wiper motor, usually found under the windshield cowl.
Disconnect the motor's electrical connector.
Apply 12 volts directly to the motor terminals using jumper wires from the battery.
If the motor does not operate, replace it with a new motor, ensuring proper alignment and securing all bolts.

5. Reassemble and Test

Reattach the steering column cover and any other components removed.
Reconnect the negative battery terminal.
Test the wipers by activating the control stalk to ensure they operate correctly.
