Water in my car!, anyone else ever have this problem? Options

[95st-celica]

alright...i had this problem before and i thought i had fixed it/cleaned it out...whats happeneing is at first i was getting water comming through the sunroof.....it must be sitting up where the hatch is or through the sail pannel...now celicas with sun roofs have 2 drain holes that go through the front of the car and dump out where the fenders are...at first i took a vacume and duct taped a straw to it to get into the drain holes and suck out all of the crud that was clogged up in there...that was last year...and i havent had a problem with it since then, up untill a few weeks ago...it came back. It got to the point that it was so bad, that when i would hit the brakes, it would literally soak the whole passenger seat, with a good amount of water...now instead of comming through the sunroof it seems to be somehow making its way down to the side of the passenger plastic kick pannel and flooding my passenger floor...i have never had this problem before and was wondering if anyone else had experienced it? and what you did to take care of it. i have to get back in there and clean them drains holes out again but i still dont understand how the water is making its way all the way down to the passenger floor.
