Scuttle off for me - good opportunity to clean out the crud underneath. Take a couple of photos so you can see which bits of trim go over and under the other - you'll need to remove (or loosen) the trim down the wings/fenders first, at least on the 8th Gen.
My washer jets weren't working correctly and seemed to be clogged (pump and hose fine). They appear to have a non return valve in them that jams up. Replacement £5 a pair ones on ebay don't have the non return bit so with nothing to lose I drilled through mine with a 2.5mm drill bit from the hose connection side (just be careful you don't burst through the top....) Flushed through backwards using the pipe from the pump to clean out the swarf, then refitted. Washers now work fine again and at no cost; just takes a second or so for the washer fluid to reach them each time.
