On earlier cars (perhaps pre-2015) the washer nozzles shoot a stream of water. This design has changed on newer cars to shoot a spray. A retrofit from Tesla is available to switch the nozzles. The cost is about $50 for parts and labor (which may vary depending on your local service rates).
Stream vs. Spray
It was reported by a fellow S owner that using a stream works better at cleaning the windshield when moving at higher speeds, and a spray works better when stopped or at low speeds, so you may prefer one type of nozzle over the other.
Can you email me what I need to replace the heated stream nozzles on a 2015 P90D model S
Sorry, I don’t know the parts – but if you contact Tesla service, they should have the right part numbers/parts for your car. Ask for the parts department.
