Rain Water in my air box....

So how does one go about stopping the heavy rains from flooding the blower motor box getting filled with water. Because when i take the turns my nice shoes get all wet!!!

drain it first. under the hood, on the firewall, there is a 1-1.5" inch comming out of the firewall. just to the right of the engine. it comes out and makes a turn down. on the bottom end there is,built into the rubber, spring holding the end of the hose closed. squeeze it to open the hose. it will be full of all kind od nasties. i put moss killer into my air intake to help the process along. add water to the intake till only clean water comes out.

I would say 9 time out of 10 it sounds like your cowl seal has went bad.

My jeep used to do the same thing, until i replaced the cowl seal. If you dont know what the cowl seal is, it is that strip of rubber that goes where the windshield folds down. You have to remove the roll cage bolts, and fold down the windshield to remove it...Not a hard job, but i think the seal is kind of expensive at 40 dollars...

for a fact i know that it is not the seal. # 1 it has already been replaced, but the water is in my blower motor area, for when i turn and the blower is on. I can hear the water splash around. I am amazed that it has not yet burned out as well. And the drain you speak of would be for the Evaporator core which i do not have. But it should at the lest work for removing the excess water. I know that the water is coming in from the top mounted air vent. But i was thinking to drill holes inside the boxed area of the vent to let water drain b4 it builds up and drops into my box....just thought there was a better way.

The air box that lets the fresh outside air into your cab is what they mean. The vent at the back of your hood has a grill over it. The drain hose gets clogged up with leaves and dirt, and will not let the rainwater drain out, hence you get wet feet when you drive it.

Open the hood and you will see a short hose that is flat on the lower edge of it. It is less than a foot long and comes from the front of this air box at the center back of your hood. You can squeeze the end a few times and all this debris will come out of it. I have had the same problem with mine, and it's a very quick easy fix.

That was the spring closure you cut off. now you may get exhaust fumes into the cabin.

HaHa, yep, that's what I'm thinking. Of course, it's just a JEEP thing.

i can always seal it to a small opening again. But was that not the hose that was supposed to be cleaned out? With the rain we had last night over here in NJ it was needed to be cut open....

Well, it was the one needing cleaning out for sure. You won't have a drop of water in it this morning. The closed end always allows water to drain out but yes it captures dirt and leaf particles, too. Just a monthly cleaning out was really all that it needs.

i can actually stuff a small section of sponge that will let water drain, but not let any fumes in. see if that works a little. cause i can just remove the sponge when needing to be cleaned.
