Leaky T-top
there is 2 or 3 drain holes on each side of the front of the car going through the rubber along the pillars.
Take ur t-tops off then take a little cup of water and pour them down each hole and see if the water runs out near your door hinges if not then they might be clogged.
Also does any of the weather stripping lift up off the metal of the roof?? you might be able to just reapply some kind of glue to get a tight seal in between the weather stripping & top of the car
