Galaxy door lock and window problems

[Madraglas]

So my ‘11 Galaxy has developed 2 problems

1 - the drives door window goes up 4” and back down and it does this 3 times before finally going up the full way

 

2 - the passenger door lock has stopped working on the remote and now has to be opened from the inside. The locking button above the door handle on the inside is slightly depressed every time. 

After replacing both the rear aircon pipes for the rear aircon this week I need to sort a few of these little issues myself if I can

Any help appreciated
