The fact that the windows go down tells us that the switch in the windshield frame is ok.

I have played around with my top and never managed to 'confuse' the system, so I doubt you did, either.

The symptoms you describe are a bad divider switch (the one on the trunk - and you often need to make SURE the arm on the divider is seated well on the switch) or a bad top switch (the one above the passenger's head - this one is EASY to see when the top is unlatched and pushed up, away from the windshield frame - be sure it has not fallen apart OR one of the wires to it hasn't broken off).

ALSO, IF the trunk is not COMPLETELY closed, OR if the electric trunk lock is not sending a "trunk lock" signal back to the TCM, you will get the beep. Trunk electric lock failures are really rare.


If fluid is low, the pump will try to run (from what I have heard from others who show up here with problems).

I'd suggest you look at the two switches Ala_xfire and I have described first, they are most likely the problem - UNLESS you have water intrusion in the trunk deep enough to get the TCM wet. You can lift the mat in the trunk and look for water in the cavities back there.
