well ive noticed that when ive got my a/c running, the condensation is leaking inside the car, and the driver side and passenger side carpet is getting wet, whats causing this? clogged up drain plug?

Yes, it is common for the plug, on the passenger side, just under the a/c evaporator. You have to remove the right side of the console panel, and with you should see a black hose going through the frame, just above the transmission. If you manipulate it, you will most likely dislodge mud/dirt that has clogged it from underneath. You might hear the water drain quickly when it is cleared out.

I've had this problem several times and when I see water on the passenger floorboard, that is the first place I look.

It is possible to do it from underneath the car, the only drawback is getting splashed by all the condensation still in the line.
