No. Only way of finding out what the problem is will be to take it all apart.

Seen this a few times on megane/scenic models.It is usually the control module attached to the motor that overheats and melts.If you are unlucky,it can also cause damage to the multi-pin connector.It is unlikely to blow the fuse ,as it is not drawing in excess of what the fuse is rated.(usually 30 amp).Not a cheap fix,unless you go the s/hand route.

Ok when you repaired it get a can of silicone spray from the tool station and spray all inside the door ,its clean and don't smell but keeps all waterproof I used it on every electrical connection on my renault !
