Yeah also started with some I bought from ebay, that were crap.
Also my headlight switch didn't work problely with the light sensor on AUTO mode....
buy from you local dealer or check ahw teile out. I did buy my headlight switch, mirror switch and all windows switches from them as it were cheaper than my local price at the dealer.
Go for the genuine parts when upgrading! :D You'll be much happier in the end and enjoy the results much more knowing it's the real deal.
