My rear screen washer doesn't appear to do anything wiper works fine I don't appear to have any leaks in the boot area that I've seen mentioned. I had to remove the sub etc anyway to remove my alarm siren after it kept going off so followed to guide on here to have a crack at replacing the battery. Had a good look around its all dry and appears ok. Discovered I have seats that need a kick to get down too and found a snap on screwdriver hidden under the sub. I can't hear anything working or see any puddles appearing outside Where should I look next for my rear washer issue does it have its own pump? Half tempted at doing a rear wiper delete to tidy the back up but had a few questions on that before I decide either way. Is it as simple as removing the wiper plugging the hole? Thanks for all the info I've gained from here so far I seem to be itching to get back and sort the little issues I have so I can get to the buying shiny bits stage!
