Pliers

2. Inspect and Replace Fuse

Locate the fuse box, typically found under the dashboard on the driver's side.
Identify the wiper fuse using the diagram on the fuse box cover.
Remove the fuse with pliers and inspect it for continuity using a multimeter.
- If blown: Replace with a fuse of the same amperage (check owner's manual for specifications).

3. Test and Replace Wiper Motor

Disconnect the electrical connector from the wiper motor.
Use a multimeter to check for voltage at the connector while activating the wiper switch.
- If voltage is present: Replace the wiper motor.
- If no voltage: The problem may lie with the wiper switch or wiring.
To replace the motor, remove any screws holding it in place and disconnect the linkage, then install the new motor in reverse order.

4. Inspect and Repair Wiper Linkage

Remove the wiper arms by loosening the retaining nuts with a socket set.
Take off the cowl panel to access the wiper linkage.
Inspect the linkage for any signs of wear or disconnection and replace any faulty parts.
Reassemble the linkage and wiper arms.

5. Reconnect and Test

Reconnect the negative battery cable.
Test the wipers to ensure they function correctly in all modes (low, high, and intermittent).
