Today I was cleaning out the truck and noticed a mois spot under the passenger floor mat. Pulled up the door threshold trim plate and find the entire carpet pad soaked there.

it hasn't rained much lately. About 5 days ago I drove thru a car wash. No leaks noted then. I do have a 3" piece of stripping damaged(see pic).

water does not smell of coolant or anything else.
This week replaced upper radiator hose, filled/burped radiator. Also accidentally unscrewed radiator cap and ran 15 minute like that around town, before the water sound in engine compartment caught my ear. Nothing else going on that seems it could be related.
been chilly run the heat a few times.
2 questions:

1) how do I dry this out? Prevent mildew?

2) thoughts on where water is coming from?

 

dry up near blower motor. Wet when it gets to the pad...reaalky wet like soaking sponge.

 

Further info...water not on top of this pad under blower...but is underneath it, in same amount as soaked carpet pad.

 

Well after some searching here and googling it seems likely that as condensation is leaking in(it's been a hell of a week, I have run both ac, and heater...but not much of either)

common wisdom says the ac drain is either blocked or poorly designed.

I found it under the accumulator. I can stick 2" of wire in it. Nothing came out and it won' go further than that.

going to try a 90 degree elbow and silicon on the outside. If anyone has dealt with this, any other suggestions?

the drain on the outside under accumulator...right?

 

Whops pic didn' work.

 

That's typically it... the condensate tracks back along the bottom of the drain and through the firewall.
Get a Dorman PCV elbow and push it over the drain (something like this)

 

Well, fingers crossed that was it. I used a heater hose with 90 degree elbow cut down to size...

 

That'll work...

 

As to water removal... borrowing the wife and daughters backup hair drier...because clearly I wouldn't own one.

 

Why wouldn't you need a hair dryer? I mean, seriously, floors get wet.......

I generally try and suck up as much as I can with a shop vac.
