My window unti is dripping water inside the bedroom room.

I was told the consensation motor? was tore up on it and that was why it was leaking/dripping water inside my bedroom. The unit was unit was tilted and sat correctly in the window. my uncle even drilled a hole in the back of it outside to let water run out and it still ran out the front on the sides inside the bedroom. I had to make a gutter thing for it out of some plastic and duck tape to let water run into a bucket. My contraption was ugly , but it worked last summer. Any ideas on how to fix this please. The unit cools great and i would not like to soend money on new a/c unit if this can be fixed....
