Air Conditioner drain

[Xman]

My truck, 1987 R10, has developed an interior leak from the a/c. I have noticed the carpet is wet under the a/c box that's under the glove box. It doesn't seem to be coolant. Where would this normally drain? Don't want the floor to rust.

There is a hole in the bottom of the A/C box in the engine bay. It's most likely clogged with leaves and other debris. You might need to pull the inner fender to get good access to it, but I'm not 100% sure on that.
