had about 600 miles when mine acted up -- both switches started doing both funtions - both opening and tilting the window.. If I closed the window and kept holding the switch it would tilt open.. Took it to the dealer - about a 10 minute fix - they stated the computer messed up - reprogrammed it and all has been well for about a year and 13000 miles..
Mine was just a glitch - your issue is probably the same.. let us know.
