need wire diagram for under seat vac pump
 

My lock quit working so I pull vac pump motor and tested.In the process unpluging the wires the longer plug went to pieces, the wires fell out of plug. I finally found problem was a door switch. But can't test until I can find wire diagrom. I searched for 3 days.

Need to know what car you are working on.

New to the forum so I hope this is ok to start here. My central locking system stopped working also. Different vehicle though, 88 560 SEL. I do not even hear the pump which I think is located in the trunk. Just not sure where. I can only manually unlock driver and passenger doors with key. Where should I start to trace the problem from. Thanks in advance for any help / solution.

my drivers door switch was to blame.
 

door switch gets worn out.

fixed
 

from bits,and photos, I managed to rewire the vac pump,I now have locks.
