I think I have narrowed the problem down to either a bad ground or a bad relay. I have a 1996 XJ. The door locks close but they don't open. Even if I jump the plug at the switch they will close but not open. I can't find a wiring diagram that will tell me where the unlock relay is or if there is one. I have seen all sorts of posts that don't help so maybe someone out there knows exactly what I'm talking about---Help.
