MBZ 350 CLK Cab top problem. Keeps saying close trunk partition

Hopefully, it is a switch, on the left side (facing the trunk,)I think, that might be the culprit. These have been known to get dislodged, or break. If a visual shows no problems, "recycle" the top by putting it up, holding the switch up for an additional 10 sec. or so and see if that solves it. If none of the above, trip to a good shop for diagnostics would be in order.... good luck

Thanks. I'll give it a try. I also read that when the springs get worn they don't push back hard enough and the switch you spoke of doesn't latch properly. You can fool it by taping it back from what I read. I'll try that if your suggestion doesn't do it.
