2007 Dodge Caravan

Hi bjulie. Welcome to the forum. Common problem; easy fix. The drain tube is blocked with debris and must be cleared. It is a rubber 4" long black or gray hose with a right angle bend molded in. One end is attached to a plastic drain pipe on the passenger side of the firewall, under the hood. The other end hangs down and its opening is molded into a thin slit to keep mice from crawling into it. It will open up when you squeeze it. You will probably have to crawl under the vehicle to see it because the engine is in the way from on top.

If squeezing the end of the hose doesn't dislodge the debris, squeeze the wire ring that holds it to the plastic pipe, pull it off, and carefully stick a pencil into the spout to get the debris to wash out, then pop the hose back on.

Thank you so much for your help. I will have my dad do this for me when I get home tonight.

Thanks for the help with the dripping water. Now my A/c is not working in the front of my van. It seems to be working fine in the back but the front just seems to be blowing air. Any ideas?

Can't say for sure about a 2007 model, but on older vans, the "H-Valve" was a common problem. If they stick open, too much refrigerant enters and the evaporator will get too cold. The condensed water will freeze into a block of ice and block air flow.

If the valve sticks closed, no refrigerant will enter so no cooling will take place. The rear unit is totally independent so it could still work fine.

Where is the H valve located?

It's a rectangular metal block bolted to the firewall on the passenger side, under the hood. Two metal pipes come out of it and within a few inches are spliced to flexible rubber hoses. The single attaching bolt is between those pipes.

Don't jump in and pull that valve off. High pressure refrigerant will escape unless it is recovered first with special equipment. Leaking refrigerant can freeze eyeballs and cause instant frostbite.

You might try tapping on that valve to free it up. If that gets the front air working, you'll know the valve is the culprit.
