Dash Air Condensation

[kennersonf]

This past summer while traveling in high humidity areas, the dash A/C ducting box was beading up with moisture on the outside and dripping down on my wife's feet. The ducting box is located under the dash on the passenger side of the coach. I attributed this to the extremely high humidity outside. Has anyone else experienced any thing like this?

Suggest you check the condensation drain tube outside on the underside of the box. Might be plugged/restricted

Nope, the drain is wide open. In fact, the drain tube is missing and I'm looking into getting a replacement.

The outside drain tube on my rig is open, but no water comes out. It drips out of the seams of the box.

Thudman,

Your drain tube is likely blocked. Mine started seeping out of the seams, so I stuck a small screwdriver into the drain hose and out came a wad of carpet fibers, followed by a gushing stream of water. Pull the little rubber extension hose off and check for obstructions. While you have it off, gently insert a small screwdriver up into the drain tube on the box and see if you find any obstructions. I discoverd the problem while pulling my soaked with water air filter out at a rest area after driving thru a rain storm. The wet filter had set off the check engine light.

My drain tube was choked off at the bottom of the tube. There is a small restrictor plug in the end of the tube...probably to keep bugs out...but that's the first place for plug up too...
