Rear screen washer not spraying water just pouring out

Hi, Its more than likely that the inner part of your jet has come out. A new jet wont be much and are very easy to replace.

how do i get the jet out then

Hi, you will need to remove the inner panel behind the washer jet. You should be able to see the back of the jet with the hose going into it. Carefully remove the hose (might be quite tight) and the jet should push out.
