Hey Chris,
Thanks for the info. A while back I sealed around the air intake under the cowel and that cut down on the water by about 90%.
I think now it’s getting in around the door (there are a few gaps I can see daylight through)
My brother lives in Nelson now, beautiful countryside there. Jealous of the snowboarding right now !
All the best,
-Dan

Came across the blog on Jeepforum.com and have been browsing it from the beginning this morning.
Wouldn’t worry about the passenger floor getting wet. Water gets in in two locations on that side of the jeep. The first is there is an air intake for the vents under the front cowel. If there is a bit of a gap between the intake and the cowel water will get in.

The other spot is where the blower fan is located which is right behind the battery. Less likely there unless heavy water (i.e. a hose). Found this one when I tried to flush my heater core.

On a side note I saw you have been to Nelson. My parents live about 7 miles out on the north shore and we are planning on going out next July for my cousin’s wedding. Beautiful country and the wife and I are really looking forward to going plus plan on moving out there from Ottawa.
Good luck and I can’t wait to keep reading especially how the jeep works for you!!

Dan,

Just found your site. Very cool.

Its likely that the A/C condensate drain is plugged. Here is what Chrysler has to say:

THIS BULLETIN SUPERSEDES TECHNICAL SERVICE BULLETIN 24-007-03, DATED
AUGUST 15, 2003, WHICH SHOULD BE REMOVED FROM YOUR FILES. ALL
REVISIONS ARE HIGHLIGHTED WITH **ASTERISKS** AND INCLUDE CHANGES TO
THE TJ MODEL YEARS AND TO THE PART REQUIRED.
SUBJECT:
HVAC Drain Water Leaks Inside Vehicle And Under Passenger Side Front Carpet
OVERVIEW:
This bulletin involves installing a HVAC drain hose.
MODELS:
2002 (KJ) Liberty (Domestic Market)
2002 (KJ) Cherokee (International Market)
1997 – **2005** (TJ) Wrangler
NOTE: This bulletin applies to LHD Liberty vehicles built prior to August 10, 2001
(MDH 0810XX), and to Wrangler vehicles built prior to March 01, 2005 (MDH
0301XX).
SYMPTOM/CONDITION:
The customer may experience a wet front passenger floor or floor carpet. This condition
may occur due to water (A/C condensate) from the HVAC assembly drain tube. As A/C
condensate leaves the HVAC drain tube, it may run back along the outside of the HVAC
drain tube, enter the passenger compartment, and run under the front floor carpet on the
passenger side. This condition may occur most often while the vehicle is being driven.
DIAGNOSIS:
Inspect for the source of the water leak. Determine if the passenger side of the front floor
carpet is wet because of air conditioning condensate from the HVAC drain tube. Inspect
the HVAC assembly drain tube for the presence of a drain hose. If a HVAC assembly drain
hose is not present, and the A/C condensate from the drain tube is the cause of the water
leak, then perform the Repair Procedure.
NUMBER: 24-003-05
GROUP: Heating & A/C
DATE: February 04, 2005
PARTS REQUIRED:
Qty. Part No. Description
1 55037651AA **Hose, HVAC Drain (KJ)**
1 56000724AB **Hose, HVAC Drain (TJ)**
1 NPN Strap, Tie
REPAIR PROCEDURE:
1. Inspect the HVAC drain tube. Clean out any debris or other restrictions in the drain.
2. Install a HVAC drain hose onto the HVAC drain tube. Once assembled to the HVAC
drain tube, make sure the open end of the drain hose is facing towards the ground.
3. Install a tie strap around the drain hose to secure the hose to the HVAC drain tube.
NOTE: Inform the customer to regularly inspect the new HVAC drain hose for debris,
especially when off-road driving is performed

Hope this helps,

Jim

It does not smell like coolant, and I’m not losing any either.. so I think it’s more likely what you are saying.
Thanks for the help!

Does the wet floor smell like coolant? It’ll be pretty obvious I’m sure… If not, also check inside the front cowling. If the drain in there gets clogged, it can back up and then down your fresh air intake for cabin air vents. You can look at the vent inside the cowling, and the plastic tube where it comes out at the bottom behind the engine on the firewall.

Hey man – I’ve yet to leave the roof down in the rain, but I’m sure it will happen sooner or later. So far so good on the major mechanical items anyway. Fingers are crossed.

Thanks for the Jeep post! I am kind of a Jeep buff and was secretly wondering how yours was holding up. My foot wells were filled with water too one time…I sorta kinda….did not umm…install the soft top correctly and well it rained that night (of course) and not just any rain- downpour- and the wells were filled up to my ankles. I was thankful for those drain plugs…I imagine that the same thing must have happened to someone that works at Jeep and they put that in the suggestion box at the Jeep plant. I am rambling.. nice post! Keep the Jeep posts coming!

Andy, Thanks for the info. I’m not loosing any coolant, which I think would be happening if the radiator core was leaking. Is that correct? Thanks.

Dan,
The passenger foot well is definitely the heater core. It happens all the time in TJs. I don’t remember the exact fix, but I’m sure a very quick search on jeepforum.com will show the answer.

And good call with replacing the radiator. They are also pretty common to go bad. They normally go bad around 75k – 100k miles. If it happens again, get a double core aluminum one
