Solution

1. Preparation

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

2. Inspect and Replace Fuse

Tools Required: Fuse puller or needle-nose pliers.
Locate the fuse box under the dashboard or engine compartment.
Identify the wiper fuse (refer to the vehicle’s manual for location).
Remove the fuse and inspect it visually; if blown, replace it with a new fuse of the same amperage.

3. Test and Replace Wiper Motor

Tools Required: Multimeter, basic hand tools (socket set).
Confirm that the wiper motor is receiving power by using a multimeter to check voltage at the motor connector with the wiper control switch activated.
If no power is present, trace wiring back to the fuse and switch.
If power is present but the motor does not operate, remove the wiper motor according to the repair manual.
Install a new wiper motor if necessary, ensuring all connections are secure and torqued to manufacturer specifications.

4. Replace Wiper Control Switch

Tools Required: Screwdrivers, multimeter.
If the wiper motor is functional, test the wiper control switch for continuity.
If faulty, remove the steering column cover.
Disconnect the wiring harness from the switch and install a new wiper control switch.
Reassemble the steering column cover and reconnect the battery.
