Question The a/c drain line on my Jeep '97 Wrangler is leaking into the front passenger side soaking the carpet. I have attempted to blow out the drain at the exterior drain line tube using compressed air, however that did nothing. I have also attempted to run a wire up through the exterior drain line tube, and this did nothing also. How do I get to the evaporator coil to clear this drain? There doesn't appear to be any access points.
Answer 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.
