Believe pump is in front of the O/S front wheel, i think it does both front and rear.
Maybe worth checking that the rear washer pipe, jet assemble is not blocked or disconnected before taking the pump out.
Have heard of some one blowing down the pipes to clear the blockage and then stuck a hose down into the washer bottle and flush the rubbish out the top.
I wasted ages blowing back down the washer pipe, it would clear it for a few minutes and then the crud would settle back around the pump intake. Tried hosing mains water into the tank and this flushed out a lot of old soap but did not unblock the pump. Gave up and paid KIA garage to have it fixed. Labour to do that (including change two sidelight bulbs) was £40.
