Sounds like another "multi-function" switch failure. I replaced mine last week ....... was at first overwhelmed but this forum is awesome with info and links. There is even a how to repair the faulty switch!!!
I chose to buy a new switch and install it (found it on a sale for like $200.00 Ebay has them for under $100). I took my old switch apart and fixed it (now on shelf for who knows what)........... I would send it to you should you desire.
