There are two microswitches in the top latch assembly. One senses when the latch is opened and drops the windows - that one appears to be working. The other starts the roof open/close process. My car exhibits the same behavior as yours intermittently, and it's due to this second switch. I think it's the one with the red plunger.

Try taking the latch assembly apart (but leaving the 3 wires plugged in) and operate the top. If you fiddle with the plastic piece pressing on the red switch (apply more pressure on it, or maybe less?), you might find that it will start working. That's what happens on mine, at least.

If ends up being your problem, 986-613-795-02 is the replacement part, which is around $60.
