After replacing the passenger SAM, I am getting a dash warning to replace the windshield wiper fluid level sensor. I have identified the part number to be 220-540-00-45, but I don't have any docs as to how to gain access to the reservoir or the sensor.

I was able to find the washer fluid reservoir, it is behind the passenger wheel well. Very easy access, there is really no need to remove the wheel you can simply peel back the plastic housing. Pictures attached.
