Solution

1. Preparation

Gather necessary tools and parts. Ensure the vehicle is parked on a level surface and the ignition is off.
Tools Required: Socket set, multimeter, OBD-II scanner, screwdrivers, and safety gloves.

2. Check and Replace the Wiper Fuse

Locate the fuse box in the Model S (usually under the dash or in the trunk).
Use the fuse diagram to identify the wiper fuse.
Remove the fuse and inspect it; if it appears damaged or blown, replace it with a new fuse of the same amperage.
Reinstall the fuse and check if the intermittent wipers function correctly.

3. Inspect and Test Wiper Motor Connections

Remove any panels covering the wiper motor for access.
Disconnect the wiring harness from the wiper motor.
Use a multimeter to check for voltage at the motor connection when the wiper switch is activated.
If there is no voltage, trace the wiring back to the switch and look for breaks or shorts.
Clean any corroded connectors with electrical cleaner and reconnect.

4. Replace the Wiper Motor (if necessary)

If the motor does not receive power or is defective, replace it.
Remove the wiper arm by loosening the retaining nut with a socket wrench and carefully lifting it off.
Unscrew the bolts securing the wiper motor and disconnect the wiring harness.
Install the new wiper motor by reversing the removal steps and ensuring all connections are secure.
