My 2005 Galaxy 1.9TDI indicators have stopped working, I changed the fuse but it was still the same, then I tried holding the indicator stalk on the left side of the steering column, in the on position continuously and it worked reluctantly, but as soon as I relaxed the pressure they stopped working. So i'm assuming that that's where the fault is. IS this a garage job or one that I might be able to do myself?
