Ok, I THINK I can list the "ingredients" for moving the top...

1) Speed under 9mph.
2) Trunk divider deployed (and sensor triggered).
3) Trunk lid closed all the way (and sensor triggered).
4) (To put top down) Release latch from windshield frame (and sensor therefore triggered, since it's lowering only that is a problem, I'd check this sensor(s)).
5) Trunk ELECTRIC LOCK deployed.*


*This is an odd one. When you press the button, the first thinng you will hear, JUST BEFORE the pump starts, is the electric cam of the electric trunk lock extending to make SURE no one opens the trunk while the lid is up! As the top stops moving, you will hear the cam retract. This asembly has a sensor or two in it to confirm that the truck is locked closed for the time the pump is running. Maybe this cam/sensor is bad.

The car uses pneumatic locks but the trunk also has this ELECTRIC lock up under the latch. The top control module (or maybe the body control module under direction from the TCM) operates this lock.

Hope this helps. MOST problems with the top are sensors or the fingers/arms/etc. that trigger the sensors. Cant remember anyone replacing a module yet. Also, there are numerous sensors on the cylinders themselves. Mabye, very likely even, a sensor is bad on a cylinder. The service manual goes into great detail about the whole system. I learned this when my electric lock assembly got a little stuck and locked my trunk PERMANENTLY!
