Question Two different door locking problems on both 190Es

My 1993 190E will not centrally lock or unlock anything. This has just happened today so I haven't been able to test anything yet. I assume it's my vacuum pump under my back seat going out but I'm not sure how to verify my assumptions. Should I take out my rear seat and hook up a Mityvac to test it? Any ideas?

My wifes 1993 190E will centrally lock and unlock all doors, trunk, and gas door with the drivers side door and the trunk but not from the passenger side door. I assume this is an electronic failure in the door since the vacuum pump is working with the other two locks. How do I troubleshoot this?

Thanks in advance,
