This has happened to a bunch of people - mine went out when the car was pretty much new - it was a microswitch in the assembly.
Dealer replaced this in my car 25167563655 but it is a $500 part - not sure if you could take it apart and fix/replace the microswitch itself, but I would try before spending the money on the whole part.
