Hello fellow enthusiasts ,on my x300 there is a cable\ wire that connects the bonnet to frame of the car it has corroded and snapped . Does this wire affect the cars electrics as I have a few issues ,ie power seats mirrors and drivers widow not working .all fuses ok.

 

It doesn't, its there to mainly shield unwanted RF signals so reduces noise, its good idea to replace it, plenty available and they are cheap but its not critical.

 

The side mirrors are controlled by a module by the steering collum

The seats have there own control and the common factor between the seat and window is the driver door control

What I found with mine was the connector socket lock bar was loose allowing the sockets to move away from connection

Someone made a set of instructions on removing the door card / panel

When you locate the heavy gauge wires to the window motor you can drive it up and down with a battery charger to confirm you have a good motor / regulator , just swap polarity to go up and down

In the end you have to press the up button for a while at the full window closed position so it learns this position

Looking for your fuses

The # 1 fuse is closest to the large B + post on each fuse box

So you have 1 - 9 row closest to the B + post on the box and the next row comes back to start with # 10
