uh i have an 89 rx7 convert and water leaks in from the driver side window is it the weather stripping or is my whole top bad? and could the hole or whatever it is be the reason my whole car fogs up?

 

my back hatch has a bad seal. Its been sitting in the garage and already has already fogged up. Sucks, I keep meaning to buy the new seal but never convince myself I need it. Then again my spare tire cubby has a good 2-3" rust hole at the bottom anyhow
