Don’t know if anyone can help,I’ve just retrofitted a rear parcel shelf with the electric rear bind which appears to be not working,I think it’s the overhead console with the blind button that is at fault as when pressed doesn’t go yellow as with the parking sensor button,it does illuminate blue when the lights are on the car but that’s all,just wonder if anyone could clarify if what I’m saying is correct,any help would be welcome.The blind I bought had been tested by the seller,all the wiring is present and I’ve checked all the connections are ok.
