I have an issue with my right turn signal. I got a message a couple of months ago saying that there was a fault but no fault was apparent. Now when I fold the mirrors in, and the indicator is flashing, it cuts out on the drivers mirror. Yet when the mirror is folded out it works fine. I have tried replacing the LED indicator strip with a new one, cleaning the contacts etc but to no avail. I wondered whether it may be an earth problem when the mirrors are folded. I can leave the mirrors out but don't see the point in that when you have got folding mirrors. I have even connected the LED strip without the mirror casing in case it is pulling out when folding but it isn't and is just the same. Can someone help please.
