water from AC

I have a 1995 Bonneville that has been leaking water inside. It is from the AC because it leaks both in dry and wet weather when I am running the AC and it no longer drips under the car. I have looked on the firewall and have not been able to see a drain tube. I read that it should come out and take a 90 degree turn towards the ground. Does anyone have a picture of where it is located? How difficult is it to get to from inside the car? I can not get under the dash like I used to because I am getting old like my Bonneville.<grin>
