Water issue:think I got this!

So, as you know, I got my 2006 TJ and noticed some water puddling in the passenger side floors....today, finally able to take time to trace where the water was coming from, behind the a/c box...this is what I found in researching.. Also mentions the cowl(surprised? lol)


97 jeep wrangler when running ac passenger side front floor board get wet whats up can anyone help?

The drain passage for the AC Evaporator is plugged. This causes the box under the dash to build up condensation (water) & flood the floor. You need to open up the lower dash & clean out the box & drainhole. If you don't, mold & mildew will grow.

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 performedJEEP PASSENGER SIDE LEAKSBeside the Service Bulletin for the clogged A/C drain, another source of leaks is attributed to the air intake box for the heater/ac. To access, remove the wiper blades and remove 4 screws on cover just aft of the hood. Open the hood and slide the hood seal (on the aft bulkhead) to expose 2 additional screws. Remove the tray and the intake box will be on the passengers side. Remove the 3 screws securing the box and remove. Look down into the intake and you will see water in the box if the foam seal on the cover is leaking. I applied silicone sealant on the foam gasket and a bead around base, as well as covering the screw holes. Re-install the box and secure. Wipe excess silicone to assure a seal around the box. No mores leaks.

Thanks for the post. Mine started doing this yesterday. Guess I know what I will be doing this weekend. I don't have carpet though so it isn't as big a pain.

I had it for a couple weeks before I noticed the 1st time, it soaked enough to get to the rear carpet, ick....so yesterday I pulled out all the rug! Finally! LOL...thinking it is definatley time to pull out the seats, carpets etc and line the tub itself....I'll be in the elements daily with it for work, so out with the carpets and in with the bed lining lol....slip proof naturally! Hard to find replacement carpet as it is a RHD...

Then it's off to vinyl seating and body armor! LOL...let the fun begin!

Glad this helped!

That's great info, I had the same problem and installed an elbow shaped tube pointing to the ground. It seems to have fixed the issue completely. Glad to know I wasn't the only one with that issue.

New 2000 TJ WET

So my jeep is sitting outside it rains really hard for 45 minutes. The next day the front carpet (driver & passenger) is soaked. The AC wasn't running the 1/2 door sliding glass windows shut & no leaks I've seen from the soft-top. It was just sitting stationary. It couldn't have even come up from underneath - it wasn't moving. Thoughts ?

It can been the door seals. Water follow the door seals down and seeps in. You can bend the tub lip upwards slightly that forces the water out instead of coming in.

my 2001 TJ leaks on passenger side through the blower motor; I traced the leak to the weather stripping along the front panels where the hood meets (near the hinges) I have yet to replace it but if I put in extra materials along the weather strip, water does not come in. Just another place to check.
hope this helps

TJ AC Evaporator Box

I realize the AC evaporator box is under the dash. But exactly where, I am a new owner.

Check the cowl drain underneath that comes from the hood cowl vent. When it clogs, the rain water doesn't drain and pours through the floor vents.
