Hi everyone, I'm having a problem with the trunk lock on my 1990 100. When the trunk lock cylinder is in the horizontal position it will not lock with the central locking system. I can usually here the trunk lock click if it locks, but it is totally silent now when I lock the doors. Are there any BTDT's on these locks. Thanks for the help. Ben 1994 90S 1990 100 1985 4000s
