poor wiper performance for refreshed Model S (windshield wiper nozzle issue)

During a recently big snowstorm, I noticed my passenger wiper has noticeable poor wiping performance than my driving side wiper. the problem is the windshield fluid can not reach the far right side of the window, resulting in poor wiping performance while the windshield is dirty (e.g. during snowing conditions).

After I back home, I've tried to use my phone (slow motion) to capture how the wiping works on my 2022 Model S and noticed that the nozzle on passenger wiper has less pressure from the nozzle than the driver side one. (see attached picture, first is the driver side wiper IMG_1245.JPG, the second is the passenger side wiper IMG_1244.JPG)

Because the passenger side wiper is responsible for wiping the autopilot camera, the poor performance of the wiping resulting the auto-pilot suddenly panic-out (autopilot suddenly quit ), does anyone else has similar issue or can take a look at the nozzle to see if such difference is common for all refreshed Model S?

Appreciate anyone's input, Thanks!

I have not experienced this issue on my S Plaid. However, looking at your pictures it appears the the drivers side washer has 4 fluid streams and the passenger side only has 2 squirting out the end.

Perhaps the passenger one has 2 ports clogged. If so a safety pin may work to remove the debris.
