Just installed new center switches and everything works but the lock switch only wants to lock all dors but drivers and then will not unlock any. Only way to unlock all at once is with front pasenger door by manually pulling up. I only have the dummy key for this car. Tried old switch with same results.
so basically when i park it, Ibhit the center lock and lock everything but drivers and have to use key on outside to lock it.

If you only have a dummy key, you will have to live with the problem as the key fob is longer made.
