After some advice guys,

My drivers door speakers don't work and lately my soft closing door has also got temperamental. Now I know there is a common fault with the wiring due to the door hinges but whats the best way to fault find the problem?

Thanks Danny

Hi

A quick way to check would be to unclip the black conduit inbetween the door hinge.
And then look at the wiring 9 times out of 10 you will find a broken wire.

Thats where i would start
