Active Aero problems

Ok, it got cold and my Active Aero isn't working. I love it when that rear spoiler goes up and down. Anyway, the dealer wants crazy amounts of money to work on it. I assume others have had this problem as well, as it's mentioned in the FAQ. Please let me know if you had this problem, what was wrong, and how you fixed it. Thanks!

However it is possible that it just froze...I mean my wipers were frozen to the windshield this morning and my passenger door was almost frozen shut...so it may come back to life with a bit of warmth. I generally turn off active-aero in the winter, just so it doesn't break...
