Solution

1. Preparation

Gather necessary tools: funnel, clean cloth, Tesla-compatible diagnostic tool.

Locate the washer fluid reservoir cap and remove it.
Using a funnel, pour appropriate washer fluid (non-freezing, if applicable) into the reservoir until it reaches the full mark.
Replace the cap securely.

If the washer pump is not functioning, locate the washer pump at the bottom of the reservoir.
Disconnect the electrical connector from the pump.
Remove the pump retaining clips or screws and pull the pump out from the reservoir.
Install the new pump by reversing the removal steps, ensuring a snug fit and secure connections.
