996 C2 Cabriolet Top won't latch

[vfrpilot0]

Odd problem this morning. I put the top down and drove to work. When I arrived at the office I put the top up and the latch in the front center of the top extends out and starts to latch, but immediately unlatches. If I hold the button down It will continue to latch/unlatch. I tried stopping it when it appeared latched, but the rear windows will not roll up indicating the top isn't properly secured. Externally the Top is taut and appears normal. The clam shell functions as it should. No strange noises, just a latch the extends/latches/unlatches. Any ideas?

The top went back down without issue.

I have exactly the same problem on a '99 996 Cabriolet. Any ideas from anyone in the forum?

I did open the latch unit but I can't figure out the order of the relays to figure out if one of them is not working or ifs something that needs adjustment.

It's probably not the adjustments, but the latch isn't activating the microswitch in the top center of the windshield. You can test it by pushing it in and seeing if the rear windows will go up. If they do then this is your problem. Here's a link to someone who's already posted about this issue...and if this is your issue the part is 9 bucks on line or fifteen from the dealer.
