Williams 3 Sunroof motor

Hi people I have searched and searched and I cannot find a replacement motor for my sunroof. I have tried finding someone who will refurbish the one I have and I can’t get it repaired either. Please can someone help me out to locate a replacement or refurb company that could fix it 🙏🏻 Thanks in advance 👍🏻

What's broken? There are replacement gear parts on eBay here:

If it's electrical/motor, I'd have thought you could try somewhere that repairs alternators & starter motors...?
