Hi all, my front headlight screenwash pump thingy leaks which in turn drains the whole screenwash bottle. I don't really care about headlight washers, all i need is the main screen wahser to work (as i understand it would fail the MOT in that state). My question is; is there a quick fix or a way to by-pass/disconnect the headlight wahser so only the main screenwash jets are working? Thanks. P.s: my A/C smells a bit like a damp dog on a wet day, think i need to change the cabin filter, where is that located ?
