I am trying to remove the hard top for the first time from my recently purchased 1992 300SL. I followed the instructions in the owners manual, but the top does not release. The switch lights up and I pull it back, I hear some noises from the trunk area as if it is trying to do something, but neither the front or back latches release. If I hold the switch a few seconds, the lights starts to blink.

Any suggestions what the problem is likely to be and how to troubleshoot it?
