I have been trying to get my central locking to work in my '84 533i so I could install keyless entry. I got the module out and the relays work (they click and you can see them move) when triggered and the volt-meter reads that it is putting out the power but it doesn't work. when I unplug the module and use wires to ground and jump it, all the locks work fine. lock and unlock. is this just a screwed up locking unit? any thoughts? thanks.
