[W126 Coupe] Seat Belt Presenter Problem

[Dick Spellman]

Hi Camran,

I really have limited experience on the sunroof where all of mine work 
properly.  I did remove a complete sunroof assembly and send to Mike 
Ramay who walked me through the r&r.  I'd say he is the best resource 
for resolving your issue.

Regards,

Dick
