2002 Volkswagen Sharan side lights

lock could be a fault barrel or lock sticking would need a check, the sidelight bulbs are somewhat of a fuckabout, best way is to turn steering on full lock, ie if your doing the osf turn fully left, it you look into the wheelarch youll see a small hatch, slide this up and find someone with slim hands to stick there arm in the hatch, 90degree turn, anticlockwise and the bulbs holder comes out. easy!!!
