Laguna II Fuse Foolishness leads to Electric Window Issue?

Recently bought a used Laguna II



The passenger window was making a harsh noise when i lowered it and was only moving at half the speed of the driver side.. It was silent when raising it though, and again, only raised at half the speed..



The car battery being used was only a 46amp so I have ordered the correct battery.. I recently disconnected the battery to do some work on the car, and once the battery was reconnected and I reset the windows, the passenger side no longer worked..



I checked the fuse box and realised that the previous owner was using a 10amp fuse instead of the required 30amp fuse, and of course, the fuse had blown.. I tested the adjacent 30amp fuse in place of the blown fuse and the passenger window worked again, but that same noise and slow moving symptom combo was present..



I'm not really knowledgeable when it comes to electrics but what are the chances that running the passenger side electric window and electric window multiplexing unit from a 10amp fuse instead of a 30amp fuse along with a car battery with only 75% of the recommended Amperage caused some damage here?



Or are the symptoms a sign of something else unrelated or, hopefully, just a sign of a bit of dirt or degreasing needed?
