Switch Unit In Driver's Door

[Emma179]

Dear all,

 

Does anyone have any tips in taking apart the switch unit from a galaxy mk 3 in the driver's door?  Hubby says it has power going to it and it has started and stopped working once since it stopped working, so seems like it might be a bad contact.  It seems at least worth a try to take it apart.  All the wires going to the door seem fine, but driver's side is not locking (front & back), windows not working and mirrors not going in.

 

Thanks in advance.
