Went to the dealer and was told it was a common problem.The guy had the part in stock but when he looked it up even he was suprised that the price was an astronomical $42.Thats $42 dollars for a little piece of plastic the size of a quarter.I went to the junk yard and they will only sell you the whole regulator arm.I paid 20 for the whole arm and took it home,popped off the wheel and popped it on my regulator arm and problem solved.
