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.

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 JEEP PASSENGER SIDE LEAKS Beside 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.
