update , after i fixed the washer fluid leak in the trunking under the air box very soon after my rear wash stopped working so investigated the connection at the motor sure enough it had come off, so reconnected it put a few mini cable ties around to hold better then started work on the rear boot lights , at first i tried to prie the surrounding plastics off with a flat screw driver ( bad idea ) then discovered take the parts off where you would take off to change your cds get your hand behind the light and they quite easily pop out , turned out both mine had the same problem = seems the posative feed wire is a tad shorter than the earth and both had come undone , plugged them back in and both lights worked
now expecting the washer system to pop at the sub will wait and see b4 digging it out
