A/C drain

[JRS]

Living in a humid climate, my A/C produces quite a bit of water. I noticed that on my 1997 that there is a short rigid drain (maybe 1/2" long) coming out of the firewall parallel to the ground, but no hose directing towards the ground. This set-up allows the water to drain onto the firewall insulation and then drip on the ground. Was there originally a hose on these trucks? can I put one on without backing up water into the A/C inside the cab?

Yes you can. I did it on my 94 Ram. It was the source of my wet floorboards too.
