Also, the rear wiper and rear defroster on mine did work without the computer being reprogrammed but the wiper was a little wonky. I would recommend testing both wipers after you connect up the pump to make sure that the washers are working properly. If i recall, when i did mine the new pump had arrows on it for what i thought was going to be front and back. I was wrong and the fluid was coming out bass ackwards.
Oh yeah, if you test the rear washer without the hose connect to anything (or run to a bottle), it will shoot about 10 yards
