RE: A.C. moisture
I had these comments in my archives:
The AC condensate drain hose comes through the firewall behind the engine. It is about 12 inches inboard of the battery. to reach it you really should take the battery out and remove that plastic partition between the battery and the engine, then you can snake you hand behind the engine and cut off the end of the hose with a razor blade.
The problem is the hose is probably 3/8" in diameter, but for some reason it squeezes down to a very small opening at the end of the drain hose, and this little hole gets pluged up and causes the condensate to overflow inside the car and get everything wet, including all the electornics in the passenger foot well area. You can also get to the hose from the bottom of the car, which may be the easy way to cut off the end of the hose. Good luck it is really tight quarters behind the engine.
Or from another member’s post:
Raise the right front of the car - use a jack stand for support. The a/c evaporator drain hose is a rubber, 90-degree hose attached to a hard plastic nipple that protrudes from the firewall. While the engine is cool, remove the hose. It is behind the right engine head. There is very little room to work, but it can be done. I used a small, screw driver size "tack puller" to help me pop the hose off of the nipple.
Clean out the rubber hose. You will probably find white, crusty material in it. Cut off the end of the rubber hose where it is molded into the size of a small split pea. The opening is prone to clogging and does not permit enough water to drain during high humidity conditions.
Use a plastic "zip tie" and push the non-clasp end into the plastic nipple. This will help clear any residual material. Replace the rubber hose on the plastic nipple and lower the car.
Although a Chevrolet dealer replaced my car's computer and reprogrammed it under the new car warranty - they did not dry out the car. When I got it home, I removed the right seat (very easy) and then the carpet/pad (very easy). I was amazed at how much water remained in the carpet and pad. I disinfected the floor pan and dried the carpet in the sun. I replaced the carpet and there has been no smell.

RE: A.C. moisture
much appreciate your tips...have followed them, yet massive water to passenger floor continued on heavy use ac trips...then dealer said it was cured after their "repair", still water continues... drain tube end now trimmed, seems totally dry,as well as the connection area...any additional clog points, etc.
thanks for the tips
