Technical Power window and mirrors not working

[Zolhaz]

2017 mod 2,3 multijet 180 hp motorhome. Power window and mirror stopped working after i change to new speakers. Window switch is working as far as i can see, but i cant find any positiv wire into the switch. There is 6 wires going into the switch and 4 of them is negativ. I check all fuses and they are ok. Is there a control box and where is it located? Can it be any relay issues, and where are they located? Anyone have wirering diagram?
Hope someone can help me out here ?

Almost certainly you have disturbed something when changing speakers.
Go back through everything you did while fitting speakers and check didn't accidentally disconnect any wires or break anything.

I already did that. No wires damage, no lose wires that i can see.. i only replaced the old speakers with new ones.

Aye I am with Jack on this. Arm yourself with a volt metre and start from the switch and make your way back.

There is some description of the connectors, function and wire colours in the "Converters and Upfitters Manual" which is the first download in the Ducato section of the Downloads section on here.

It is for the 2016 onwards model, and Section 3.61 onwards is relevant to the door switches.

A quick read leads me to believe that the window circuits are possibly pulled to earth by the switch to complete the circuit (which might explain your measurements), I don't think the mirror circuits are the same, though.

May be of some use. Pre-facelift model but I doubt much has changed
