Swift Sport window issue

[iwf 55]

hello all, have an issue with drivers side window on my swift in that it will not open. one blown fuse has been replaced which sorted the problem for a couple weeks, now its happened again. Passenger window operates normally with no issues, but drivers side is a non mover, fuse has been checked and double checked but it's ok. any thoughts or suggestions of cause and subsequent fixing.

regards
