I have a the usual problem with boot not opening replaced switch and latch wiring is fine I think the roof control unit is faulty as telling body control unit not to let boot be opened when roof is down but my roof is up was wondering if any one has the wiring diagram for this as its a lot of money for new roof control unit. Can any one help or tell me of a way to diagnose it I've used diagnostic machine with live data and the fault in body control module related to roof but want to be 100% before going for it.
