Welcome tellyus.
I don’t know enough about the subject to give any specific information. I do have a suggestion though. Did you check the sunroof track microswitches? They will cut the power to the motor when roof is fully closed or open. If they malfunction they would interrupt motor operation.

Gentleman,
Finally, I fix my sunroof & shade problem...
1) Replace,bushing,bolt & gears (AliExpress.com)
2) Reassemble and reset the sunroof switch.
3) It's just working find...

Tip
1) I have a power issue with the front sun shade,but after resetting the sunroof switch, I have a power back on.(I accidentally reset the sunroof switch....hahahaha)
2) When you replace the sunroof motor gear, you need simple tool from Amazon $17. (In my case, I just paid $50 to replace gear at the local mechanic shop)
Total cost is $ 120. but, if you are done by a local MB shop, It will be a fortune...hahaha minimum $2k....easy
Good Luck Guys!
It's easier than what you think! Go for it!
