My cable in door broke, the dealer is telling me it will cost 420.00 to fix, is this right? seems like alot
Does the door open from the inside and or does the door open from the outside? In either case the interior door trim panel has to be removed. The inner plastic housing on the door trim panel that opens the door and the outer door handle are expensive to replace, perhaps it is only a plastic linkage clip that is broken but removal of the door trim panel will be necessary to figure out exactly whats broken.
That price may well include the door latch. Perhaps they are considering the possibility a binding/stiff latch caused the cable to break.
