Rear door no electrics

[Nathan Anglesea]

Hi, can anyone help? I have a 2007 w204 200cdi, my rear door electrics passenger side have stopped working, well light not working (new bulb) and window controls don't work. The window will work from the main panel on the drivers panel though, central locking is working fine. Is it a fuse that needs replacing for the door electrics?

Hi,

Could it be as simple as a broken window switch in the door and a duff pin switch on the door frame.
I don’t think there is a fuse for the door and if the window works from the drivers door there must be power to that.

It just seems a bit wierd that the window control and well light both stopped working at the same time?

Might be a broken cable in the conduit from car to door, loss of a supply to a control cct. Difficult without a wiring diagram.

Both at the same time I would be looking at the earthing on both.

How would I check that?

How would I check that?

Take the window switch apart, see there is power coming into & out of the switch. Then check the earth which is possibly on the motor.
Check the door light contact switch is going to earth.

Wiring in door t door pillar or earth wire off or broke.
