If the top won't move, I'd bet water got into the CLP/SSM. I've fixed three Roadsters that had this issue, all three times, I replaced the CLP/SSM and last three feet of wiring harness, parts taken from a donor car.
Fixed it every time. The module and harness will run $100-$300. Labor takes less than two hours.

First, ya gotta source a new top. I prefer BAS tops in the UK. About $850 delivered, they are 6-8 weeks behind right now.
There are a few other manufacturers out there. I will let Zach know you are looking for help, he's one of the east coast guys that fixes our cars.
