1994 Sunbird-a/c leaks into passenger compartment-cannot find drain?

I believe the drain on the a/c is plugged but I can't find it. When I use the a/c moisture soaks the carpet on the driver and passenger side. I don't see any water draining outside the car. Is this something I can repair myself?

HI ,I think you identified the problem,blocked drain.I would carefully pull the fire wall insulation away from the interior passenger side of heater.The drip tray should be on the floor under the heater.Some thing is blocking the drain ,piece of insulation probably.Was any work done in this area?If you can get under the car ,you could run a wire up the drain pipe to clear it.Good Luck.
Reply:Raise the hood and look along the firewall for the drain hose. You can run a small flexible tubing into the drain and unclog it. I wouldnt recommend using a wire, because that could puncture a hole in the hose.
