I have an r reg mk 3 van 1.7td. None of the centre console lights are working and the heater fan doesn't work no matter what you do with the switch. All fuses checked out ok so I took the radio out and noticed that there are 4 terminals on top of the heater fan switch. 2 off to the left on mine have wires connected the 2 in the middle have nothing connected are they meant to have something connected? Have had a ratch around in the hole but cant find any surplus connectors. Just like to know before i try the next port of call under the scuttle panel to visit the resistance.
