Re: Auto Spoiler Switch gives me blinking light...
Mine did that too. The BAS/ESP light also came on. I did the reset listed in our owners manual and it stopped. KOW that was two years ago and I had spun the tires on a wet/icy road coming out of the office parking lot. Try the reset, its listed as reset BAS/ESP. Very simple to do, may take a bit for it to actually reset. I did it when I came back from lunch and it didn't reset right away, by the time I left for home it was fine. I had already made an appointment with the dealer to look at it which I cancelled. I also agree with CRM, that is another cause.
Hope it works for you.
