Hi the interior boot release button and keyfob boot release button have suddenly stopped working on my wifes 55 plate sportKa, the central locking for doors are working so its not the batteries in the keyfob, Also read that if the rear windscreen wiper isnít working then it could be a fuse but hers is working so donít think its that but could be wrong but I donít know which fuse it would be, has anyone got any ideas on what may be up with it?
