Not sure if the top operation changed in 04 (as compared to my 01), but it probably isn't as simple as a console switch.

First check if you can raise or lower the rear headrests...they act as a rollbar, comparatively speaking, to the SL-series. If you can't get them to move, the entire top operation is halted. This happened on mine once, and dealership replacement of the pump and motor (one-piece unit) was a $2700 burn in my wallet!!!

Second, there is a cable in tension that tells the system how the top is oriented, so that is knows when the operation is complete. Mine is a bick slack, and I've found that I can "coax" the top a few inches back in order to get the top down operation to finish the cycle. This is a far cheaper fix.

Again, yours might operate differently, so I can just comment on what has happened for me...
