I'm not sure, but I think even though you're not using the heater, the water is still passing through it. So in essience, if the heater core is bad, then it would leak into your floorboard. Everytime I've seen that problem, it's been the heater core.

 

It wouldnt happen to be that black box behind the glovebox would it now?

 

I'm not 100% , but according to my Hayne's manual (please don't let me get flamed for that) I think it is. It shows an illustration with the heater core being inside a box underneath the dash. If it is in fact your heater core, your whole dash assembly is going to have to come out.

 

ahh jesus f'n christ! WHY does Murphy have to move in on me?

 

did you ever figure out where the leak was coming from?

 

no, the humidity bucket is still trying to do its job, once the floor is dry ill go up under.

 

yeh thats the heater core... did you get a foot full of anti freeze? lol anyhow if your heater core went up your car would probably overheat too...

i took one out of my 87 jeep wrangler, it was a pain in the ***.
you have to take out the whole black box, to do it i had to take off the bottom part of my dash...

once you get the black box out, you gotta open it up and inside is a "mini-radiator" aka a heater core, so you just pull that out, but be careful not to get antifreeze all over the place... then once the new one's in, just reassemble the black box, then remount it in the dash, and make sure the heatercore pipes go thru the hole in the firewall

 

nah, anti freeze is nowhere to be found... Im still waiting for every drop to be absorbed by the humidity bucket. Im going to shap vac it tomorrow

 

I have water in my floorboard too! But mine is in the drivers side floor board....
What do i look at to find where its coming from?
I spent all weekend with the shop vac and leave blower trying to dry it out.

Any help is appreciated.

 

If it's condensation from the A/C system, then you've got a problem with the drain tube. From under the car, you should be able to access the evaporator drain. It's a rubber tube, usually on the passenger side. If you GENTLY run a coat hanger wire up the tube (not too hard because you can poke a hole in the evaporator) you should be able to remove the restriction. Just leaves and junk that collects at the bottom.

Hope this helps! Good luck!
