89 300e doorlock trouble
 

I have a 1989 300E and in the past had intermitant door lock touble. I now have no automatic door locks. There does not seem to be any power to the pump under the back seat. I can follow the power wire only so far without ripping stuff out that I do not want to damage. Can anyone tell me where this pump gets its power from, like where the bus bar or terminal is. Thanks.

Central locking
 

Power comes through Fuse A and C and goes to X 30 (under left side of drivers floorboard). The wire from fuse A is Black with yellow tracer and the other is red with white tracer.
x1 is a three pin connector at the pump where you can test these wires.

Thank you Mike. As soon as its above -30 I will check if that wire is in good shape.
