Sunroof will open, but won't close

[ericcrews]

Hi all - new to the forum and to Tiara boat ownership as of 2 weeks ago!  I just bought a 2016 Coupe 44.  The sunroof opens with no issues, but we can't get it to close.  Our mechanic has spent over 40 hours trying to fix it, but still can't - he has called the Tiara tech people, etc....  No idea what to do.  Anyone else ever have a problem like this?  Grateful to be part of this group, and for any and all help!
