- Wiring diagram for the Honda Accord
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Replace Wiper Switch (if faulty)

Remove the steering column cover using a screwdriver.
Disconnect the wiper switch connector.
Unscrew and remove the wiper switch from the steering column.
Install the new wiper switch and reconnect the connector.
Reattach the steering column cover and secure with screws.

3. Replace Wiper Relay (if faulty)

Locate the wiper relay in the fuse box (consult the owner's manual for exact location).
Remove the faulty relay by pulling it straight out from the socket.
Insert the new relay into the socket, ensuring it is seated properly.

4. Inspect and Repair Wiring (if damaged)

Inspect the wiring harness for any signs of wear or damage.
Repair any damaged wires with appropriate electrical connectors.
Ensure all connections are secure and free from corrosion.

5. Test Wiper Motor Functionality

Reconnect the negative battery terminal.
Use the multimeter to check for voltage at the wiper motor connector while activating the wiper switch.
If voltage is present but the motor does not operate, replace the wiper motor.
