Hello people, In my V40 neither heating nor air conditioning works, blower runs, switches to circulating air. Would you like to order a control panel (see photo). However, I still have Shzg. and DSC. Can I simply install and connect the switches or is it not possible if the control comes from a car, which was ordered/delivered without these extras? Could something else be defective if there is no warm air anymore? I suspect/hope that it is only the controller itself. Can’t hear that something is being adjusted. At least it was put on cold before it failed the service. Thanks in advance curnik
