The seat belt extenders on my vehicle are working perfectly in every respect except that they will not operate when the seat belt extender button on the console is pressed

i have just had the vehicle connected to the MB diagnostic software and the report is that there are no electrical components at fault

It also states that the extender button is working

They are now going to look at wiring diagrams etc to see if they can find where the problem could be

Does anyone have any idea where I can start looking?

If anyone has a wiring diagram covering the seat belt extenders and the seat belt extender switch that would help
