Hello, just got my first Citroen and there are a few things to sort but the main one it the left indicator staying on all the time. Removing the switch, the flasher can and the key has no effect. The right indicator works properly but the left tries to flash but cant as its already on. Any ideas where the fault could be, is it a new one or a common problem. I know its probably a wireing fault as everything else has been removed. The car is a 96 Volcane TD.. Thanks in advance for any advise.
