When i connect a trailer a get no turning lights on the trailer. Have tried different trailers, so the fault is in the car.
There is a red relay above the rear ligths wich give strange sounds when connection a trailer and using the turning lights. This relay were very expensive to replace with a new Ford original and the repair shop was not sure it was this relay causing it.
Any thought? Im thinking of going to scrap yard to test with a used one, however the ones close to me didn't have one.
