Passenger side head light malfunction. Head light works on and off; does not turn on sometimes. Some days it works, some days it never does. Problem appears to be related to rainy/dump weather. Dealer did not acknowledge that it is wiring issue and recommended that the hole system be changed and it cost me $909. 00. They did not give me the old part.
