I need help with my left passenger window...

[toyota]

Can anyone please help me out? I currently own
a 2007 yaris sedan, and a couple of days ago my
automatic button from the driver's side to roll down
the window to the left front side passenger's side
was completely stuck, as if it was a piece of
plastic, that has never moved. I pressed it really hard
and after a couple times it finally was able to move
my window, but very slowly.

like 20 mins later i got off to go to the store and when
i came back, there was a burning smell, kinda like when
metal is getting burned or something similar to that.
then i tried rolling down my window from the driver's side,
and it wouldn't work, i tried it from the passenger's
and it did, but very slowly.

later on i got home and tried it again, and nothing, it would
not go up or down from either side. not from the driver's
side nor from the front passenger's side whatsover. all my windows
work, they go up and down from the drivers and their sides
except for the one in the front passenger, that one does not

Has anyone else had this happen to them, if so, can you
please tell me what to do to fix this?

i would really appreciate it greatly. thank you!
