@Swede334 My post #2 is not correct. It seems the mechanics of the latch hasn't failed, but there is a small switch in that latch that does fail and it is an important part of the top opening and closing operation for the roadsters. Have you tried to order the part from the link I provided you??
Here is a link to the same problem you are experiencing. Read through the entire thread, do not jump to conclusions as the last few post are very important:

Good Luck!
