Air Conditioning water leaking into passenger side of cabin 2002 KJ cherokee

[jtg1231]

I have a heap of water on the from passenger floor(no rain) so I suspect it is coming from the air conditioner drain. Anyone tell me where the drain is located and can it be unblocked or renewed without having to pull half the car to pieces to get to it. Thanks.

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.

Thanks to those who replied. I think I should be able to fix this one.

[jtg1231]

We ended up having to vacum out the discharge pipe at the firewall. Poking a wire in didn't help. We added some silicon tube and cut it off just before it appears below axel level to ensure the water drops out of the engine bay, securing the tube to the A/C outlet with a tie wire and an extra one furtherdown the silicon tube so it will not move around. Thanks for the input and thanks to my brother John who always seems to have some sort of answer to these questions. He uses tie wires for everything.

PS if you ever need an oxygen sensor my brother can get probably get them at the best price.

Yeh I remember doing this to my cousins 03 KJ using garden hose, track repairs while offroading.

He just searches them out. He seems to know who when he needs to.

I know this is an old thread, but does anybody know if this service bulletin was possibly a recall?? I just found out my TJ is doing the same thing and when I inspected the discharge hose, it's a straight hose out of the firewall. According to the service bulletin it should be pointing down to prevent the water from leaking back into the cabin.
