Yea, I just bought my 05 and the top only goes down when it feels like it. I can't figure it out. How many sensor switches is there? The rear trunk shelf sensor tests out ok, there is one for the rear top latch, and I haven't found one for trunk lid, How many is there? When it works, it works fine for a couple days. Then it won't. I know the dealer is going to charge me a lot to figure it out. Help.........
