Washer fluid low message came on in my 05 xlr. When I checked the level, I thought it was pretty high for a message to come on. Anyway, I filled it up and when I did, something floated up to the top. It was a green round plastic part, about 1 1/2 inch long and 3/4 inch in diameter, with a slot in it and what appeared to be a small rectangle magnet in it. Does anyone know if this is part of the level sensor or is it something that just got into the washer container. I had not filled up before so did not see it. The low washer level message is still on also. I am going to take the container out but just wanted to know if this part had something to do with the level sensor system.
