is the cabin air filter on the passenger side? look at the cowling under the hood, and see if the cabin air filter has shifted forward. I have seen that on my car, and when it sticks out of position, water will run in the cowling and drip on the floor
check for blocked drain in the ac box and hose to outside . Check for core leak in heater core or loose broken heater hoses. . Finally check for rusted chamber at the base of the windscreen where the cabin air is allowed to get into the cabin.
Look under the passanger side of the car,There should be a drain hose next to the firewall thats sticks down,It should be a black hose or tube that is cut at an angle on the end,pinch the bottom of the hose and see if warter darins out of it,if it does use small wire to clean inside of hose(evaporator hose)
This could be a sign the heater core or hose has gone bad and is leaking into the cabin since it is located inside the dash ifs its antifreeze it will have a sweet smell. It could also be your AC condenser, or possible window seal.
The a/c drains the condensation water out thru the floor by a small hose or tube. If you look under the van near the passenger side floor at the firewall you should see a small tube and it may be stopped up. You may have to put the van on a lift to find the tube.
Is it soaked with water or antifreeze? Hopefully, it is water. If it is antifreeze you need to have the heater core replaced. If it is water, the culprit is a clogged AC drain line. You should be able to find the end of the hose under the car somewhere directly under the heater/ac unit. It is usually a rubber hose with about a 3/8 inch inside diameter. They get clogged at the AC with dirt and dust. You can try a very flexible wire or use a turkey baster and pump water back up the hose to force the clog up. You may have to do that several times since the back flush doesn't get the clog out, Hopefully it will break it up and the water will flush it out. Some times the wire works better. Be careful not to use anything that might pierce or cut the hose. If the car has a cabin filter in the heater/AC blower, be sure it is clean. Replace it if necessary. Gaker
first, when I read your post I remembered that if the ac drain hose (small hose stub on the engine side of the firewall, usually on the passenger side) gets plugged this can happen. If that doesnt fix it, get a friend to spray with a hose and start looking for where the water is entering the cabin. Leaks are a real pain to find, even for shops, so don't get discouraged if it takes a while to beat this!
