Power Window problem, switch possibly to blame?

I have a 93 Civic Coupe.
I have read the posts on how to make your window glide up and down better, but this isn't relevent to the problem i'm having.
I have power windows, and on the drivers side, when i hit the switch for the window to go down, it goes down. But when i hit the switch for it to go back up, it just sits there, unless i move the switch back and forth, or just hold it. Doing this it eventually goes back up. I'm almost positive its the switch itself, but i'm not totally sure considering that if i hold it it works.


Please help.
Thanks
