Solution
1. Preparation
  • Gather tools and parts: OBD-II scanner, multimeter, socket set, replacement fuses, and wiper motor if necessary.
  • Ensure the vehicle is parked on a level surface and the engine is off.
  • Disconnect the battery to prevent electrical shock.
2. Inspect and Replace the Fuse
  • Locate the fuse box (typically under the dashboard or in the engine compartment).
  • Remove the cover and find the fuse for the windshield wipers (refer to the owner’s manual for the exact location).
  • Inspect the fuse: if it is blown, replace it with a fuse of the same amperage.
3. Test and Replace the Wiper Motor
  • Reconnect the battery and use a multimeter to check for voltage at the wiper motor connector when the wiper switch is activated.
  • If no voltage is present, trace back the wiring to identify any breaks or shorts.
  • If voltage is present but the motor does not operate, remove the motor from its mounting:
    • Disconnect the wiring harness.
    • Remove the mounting bolts using a socket set.
  • Install the new wiper motor:
    • Position the new motor in place and secure it with the bolts.
    • Reconnect the wiring harness.
4. Inspect and Repair the Wiper Linkage
  • If the wiper motor is functional, inspect the linkage:
    • Remove the wiper arms by pulling off the caps and loosening the nuts with a socket set.
    • Remove the cowl cover to access the linkage.
    • Check for any binding or disconnections in the linkage.
  • Lubricate moving parts if necessary, or replace any damaged components.
5. Reassemble and Test
  • Reassemble any components removed during repair.
  • Ensure that all connections are secure and no tools are left in the engine compartment.
  • Reconnect the battery.
