The rear passenger side indicator is taking funny turns :x . It speeds up and goes mad, only the one side though, the other side is fine. Dash warning light comes on check bulb but it seems ok and works fine then a bit futher down the road it does it again. The garage has had it in to check and it worked ok for him. Then we got the car back and it starts again. Has anybody else had this? Husband asking should he just replace the whole unit now or leave it to see what happens?
