In my 2004 (Monaco built) Marquis the blinds were made by Hunter Douglas. I recently had to have a motor changed out because it would not open the Roman shade. It would close just fine, but not open (lift) it. I contacted the Dealer Service Center (DSC) in Arvada, CO (essentially Denver) for the change. The DSC located a new motor and installed it, then returned the shade to me at my home address. How I found out who made the shade was to remove it from the window. On it I found a sticky mailing label with the manufacturers product ID info. The cost was just under $150, not including my freight to send it UPS to Arvada. I found "DSC Window Fashions" using a Google search on the internet for contact info.
