Repair of power roll up doors

[Wanderlust Gnome]

A few years ago purchased a Yamaha 2016 cart with pre-installed power roll up doors.
Great idea! Very unique. The only problem is when there is a problem the vendor where I purchased the cart from does not have anyone capable of repairing the motor or remote FOB receiver assembly. They will tell you they have someone trained to work on them but they only work on the channels where the mechanism slides up and down. Does anyone have any idea where to get assistance with repair or replacement of the motor/remote FOB receiver. I understand the person who designed these lives in the area just south of Spanish Springs (Del Mar). I would appreciate any suggestions.:ohdear:

I am a retire electrical engineer, I may be able to help. I would need to see the cart or the components to see if I can find replacement parts. Send me a private message with your contact info so we can get together.
