Greasy Honda Civic Windows?

I have a 99 honda civic hatch CX, it's a 5 speed with power NOTHING except brakes (it does have cold A/C, thank god). Anyway, I'm getting this terrible grease on the inside of the windows when rolled up and down (worse on the driver's side), very sticky and disgusting, fast orange will take it off with some work but ruins the tint, any idea on what is causing this?

Take the door panel off and see if you can see anything down in the door.

Leave door alone… Odds are its antifreeze from bad heater core

My guess would be leaky heatercore.
Might be just a very tiny pinhole, but enough to let some antifreeze-steam out.

Check your level

Thanks for the suggestions, never occurred to me it might be heatercore… I live in miami and have never had the heat on. I was thinking it might be that second "lip" (below the door line) honda is famous for, thought it might be turned up and dragging on the window, and it is a 16 y/o car
