Might be best to first check with a meter if your getting power to the blinds, its easier than removing them! The front switches which do them in pairs have a habit of getting dust and dirt from the re-circulating air con over the contacts and if not used on a regular basis will cause problems ...

Hi Bongonaut, any chance you could share the pic about the servo drive you mentioned . Where is the drive actually located , I can't find it.
My blinds are not working at all, I checked the fuses and switches, all ok. Blinds are not moving. Any ideas?
Thanks
