Do you have a rear window isolating switch on the centre console?

There is a switch on the dashboard to switch the rear windows off but that is not the problem, thre are switches on the centre consol which I checked and there is 12 volts but no power at the door switches, it was sugested that the wire going through the rubber pipe at the doors could be faulty but is it likely that the two doors would be afected, the car has only bone 65,000 mls
