Can my landlord make me pay for repairs to a window that already had damage? He claims that I damaged the window more after I opened it.

He said that I shouldn''t open any windows, that the storm windows were also broken... But didn''t disclose this information beforehand... It seems as though he knew the windows were in bad shape, but neglected to inform me that he had yet to make repairs... There is a large crack in the bottom of the window frame that was present before I touched it and anyone looking at the crack can see that it has been painted over many times. I am worried that he will try to take the $ for the repairs out of my deposit. Thank you.
