Disconnect the battery to prevent any electrical shorts.

2. Check Washer Fluid Level

Open the front trunk (frunk) where the washer fluid reservoir is located.
Remove the cap from the washer fluid reservoir and verify the fluid level.
If low, refill with appropriate windshield washer fluid.

Identify the washer pump fuse using the fuse box diagram.
Remove the fuse using a fuse puller and inspect it for continuity.
If blown, replace it with a new fuse of the same amperage.

Reconnect the battery and activate the windshield washer system using the vehicle controls.
Listen for any noise indicating the pump is working.
If the pump is silent, proceed to check electrical connections.

5. Inspect Washer Fluid Hoses

Follow the hoses from the washer reservoir to the nozzles.
Look for kinks, cracks, or disconnections.
If damaged, replace the hoses with new ones.

6. Clean Nozzles and Test

Using a pin or small needle, clear any debris from the washer nozzles.
Reattach any hoses that were disconnected.
Test the system again by activating the washer fluid.
