Hi all. Been out in my 2000 defender td5 today. Suddenly I noticed that my left indicator was just on but not flashing, also my wipers wouldn't switch off and my windscreen washer just kept running until it emptied the bottle and the pump kepted going. Got home and the realised the engine wouldn't stop when I turned the key. Had to choke the engine and disconnect the battery to get everything off.....any ideas?????
