Switch or Vacuum Pump?

My automatic door locks on 95' s420 MB are not working neither are my back up (antennas) or my automatic trunk latch.

Questions:

1) Are these symptoms all related to a bad vacuum pump?

2) How do I know which one is defective the door lock "switch" on the center console or the "Vacuum Pump"?

3) How do I remove the "upper" half of the center console. I already removed the bottom half but the top half...I have no idea. Are there more screws not visible? Are there special tools that I need? Do I have to remove the radio first?


Please Help.

Thank you in advance.
