Re: Light on on the top sw and spoiler won't wk
Well, often the light staying on means that the control module doesn't think the top sensors are indicating a fully open or fully closed top. I had this once, but cleared it by cycling the top up and down.
I do agree with your assesment, but one thing: Try putting the top down manually and THEN see if it will go up. This may clear any sensor confusion.
Other than that, your idea might be it.
