I have a 2005 Tucson. I found a lot of water leaks onto the driver’s side. I removed the carpet and I figured out that the leak is probably from the drain hose under the dash but after I checked the tube which releases water out of the car I found it’s Ok and has no clog. And after I took the car to the repair shop, he said the leak is from plastic box in which is directly connected to the drain hose. “The tube” he said maybe is full of water or the box is cracked and needs silicon or cold welding. But I don’t feel that he really could see the cracked area because the box is in a very narrow place as you now, and I am afraid that removing the whole dashboard is needed to fix the problem. I really don’t want to remove it, so I need your advice on how to fix it without removing the whole dash. And does silicone really work? And does cold welding work for such cases. Thank you so much.

The "silicone" referred to is a gasket sealer in a tube that cures in less than an hour to a fairly hard rubber. It is real good for forming a seal on broken parts, but only when there's no stress pulling them apart.

I find it odd that the drain pan would be cracked. There isn't any stress on it. I doubt you would see a crack without taking the heater box out of the dash.

I agree with it being odd that the drain pan would be cracked but the only explanation I would have is if there was a clog, and the drain pan was filled with water, and depending on where you live, the temperature dropped below freezing especially overnight. This could possibly cause the pan to crack. Thats kind of a long shot but its theoretically possible. As to seeing the crack, you can actually see the area where the drain tube comes out of the pan and runs outside of the vehicle. You have to remove the side panels where your feet go but you can only see a minimal amount of it.
