I don't think you will like hte price of a new pump. Do what so many do: Find a parts car and buy a used pump (just not one from a car rear ended, or a convertible that was left with the top down!)
They are generic, even between coupe and roadster - the unused console line is just plugged at the pump in the coupes. They are not VIN specific, either.

THe top not going down can be caused by the bad controller/pump, because the top wont move unless a CAN bus signal is sent to the Top Module telling it that the trunk is closed.
Or, it could be your top module got wet, but it sits awful high, higher than the "floor" in the trunk.
