I am having trouble trying to get my left hand rear door to lock and unlock . This is what i have found so far , door unlocks and locks using sill button only , lock motor is okay checked by applying power to it, door ajar switch ok . Now this is where i am stuck checked output from becm no lock signal but has an unlock signal when using remote lock or key lock . All other doors work as they should. Problem started when i was randomly blowing fuse no 14 after removing door trim found bare wire going to earth fixed this now lock doesn't work .
