997 cabriolet latching issue

[Ed997]

Hi fellow Porsche owners please help me!!!! 

My 997 2005 cab doesn't seem to want to latch. It tries then unlatches and tries to latch again and won't stop this until I take my finger off the switch. I am do this at a time of roof closed tight but obviously it hasn't finished naturally so won't let me operate the windows and the note on the dash says convertible top not in limit position. I did see a similar problem on the 996 forum bit that was to replace the plastic cover on the latch hook. I don't think they have that on the 997 plus my latch does fully go in the hole and trigger the switch I can hear it click. I have also metered that switch and it is open or closed. Have I missed something here? My indie has put the roof through a calibration and nothing flagged up. Any ideas welcome please peeps. :)) Ed.

Sorry to revive this thread - Facing the same issue, working at an indy right now lol.  Did you by chance get an answer for this?  I have ruled out a bad microswitch, resistance is fine to the rear ground point, and pins 4 and 17 on the CVT top module.  I'm going to try a module from another cab, but everything is working fine, it just won't stop trying to relatch.

Same problem I believe (1999 911), latch keeps cycling, rear windows don't close.  As a test I cut a piece of plastic and double face taped it on the switch contact site. Everything worked perfectly!   It took about 10 minutes.  Now to make the fix permanent.                                     So happy.  I bought a relay switch to troubleshoot that i don't need now, but I don't care! 

 

First time on this forum. Thank you RennTech

@Ben Bshara checking in a couple months on to see how you resolved this for your client. I purchased the windscreen latch micro switch for my 997 but am hesitant to try the DIY since your post said you’d ruled out that piece of hardware.
