Hi, my rear diff lock button on my 2018 T6 4M camper conversion currently does nothing, pressing the button does not light up the button itself or the light on the dash.
I've checked the button with a multimeter and it is working correctly and also shorted the switched wire to the button too and this doesn't work either.
Solenoids under the passengers seat have been replaced and I've verified there is vacuum from the engine.
All fuses have been checked and there are no codes or warning lights. Removing the fuse for the haldex module gives ESP warnings etc so I would assume that's working correctly.
At a bit of a loss of where to go now as there is nothing I can find online of anyone with the same issue (button doing absolutely nothing). Has anyone experienced this or would know where I should go from here?
Thanks.
