    Default Leaking dash

    Okay guys, a buddy of mine and myself were looking at the fresh air intake as JavaTee suggested, and notice that we can't find the hose on the inside of the cab that he was speaking of. I found the one that runs from the cowl back into the engine bay (Photo 1), but can't locate the one that runs from the inside back through the fire wall. Photo 2-4 are the fresh air box on the inside, and the mysterious and illusive hose.

    When the water runs, it comes as far as the radio opening (which has nothing in it.

    the hose should be here:



    your's is missing. Make sure the small angled tube is free of debris, it's the drain that lets out rain/melted snow, etc.

    CJ's are notorius for leaking, from the cowl seal, to the windshield seal, and the fresh air intake.

    You may have to take off the grill, on the center of the cowl, and see if the intake plenum is installed and sealed properly.

    Usually if it's dripping by the radio hole, thats the culprit.

    The fancy stainless or chrome aftermarket hinges for the windshield? They suck! (not sure if yours have them, but they are a leak point) They are not as tight a tolorance as the factory hinges.

    And when the windshield is up, they don't 'squish' the cowl seal enough to seal out the weather.

    There's also a small (1/2 or 3/4 inch) hose under the battery tray. It will be below the fan motor, and look like a little "L".

    Make sure it's clear. But if your dripping at the radio opening, it's either the cowl seal (between the windshield frame and tub) or from the fresh air plenum (the drian for this is in the green circle)

    The hose is definitely free of debris. I checked via the method of Jason Biggs inspecting the apple pie in American Pie while laughing like Beavis and Butthead. So since the intake hose is good, then I need to do windshield and cowl seal. How hard are these to tackle? I'm sure I'll have to get a pro to do the window one. I don't want to bother putting a radio or anything in then having it crap out when it pisses outside.

    The cowl seal at the bottom of the windshield is not too bad to do. I agree with you, don't try to do the glass seal yourself; you'll be buying another windshield.

    So all i do is drop the windshield and replace the seal? I tried to unscrew it, but it was going to take more motivation than i was willing to give it

    Thanks for the memory HillBillE, Chris remove the six or so screws holding the grill on the cowl and use some weatherstripping or silicone to make that area watertight also (where the fresh air intake attaches under the sheet metal). (It's the things after a CJ refreshening you would like to forget ).
