There is a water leak, when raining, on the passenger side. Tubing clogs eliminated. Windsheild intact and sealed. Heater box in question and seals. Any other possibilities and can the heater box be resealed without costing a fortune?

Hello -

Thank you very much for the engine info. Yes I understand your model is a Jeep Liberty, but there are three different models. The Limited, Renegade or the Sport. I will provide you info on the Limited model.

Water leaks are going to be tough and may take you some troubleshooting time but you can track it down.

First.I understand you have the leak only when raining. You have checked the tube, eliminated the windshield. However, I did review all of the TSBs for your vehicle and they do discuss a leak at the tube that makes the passenger side wet. I still suggest you verify or even "preventively" fix that so there is no question there. Here that is.

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.

Next - the best way to do this is to take a water hose and turn on slow and have someone on the inside of the vehicle with a strong flash light watching for when the water comes in.

Start low and work up and move slow. Go to the engine area first and let the water run down the firewall over the different items that go through the wall.

If there are no leaks there then close the hood and go to the base of the windshield. I have seen the body seams in this area on some vehicles allowing small leaks. Again, let the water run but try to keep to a small area at a time.

Work your way up to the windshield then move to the side A pillar of the door jam. There have been times I have had to pull the carpet back to check as the water runs. Sometimes you can see a rust or dirt trail that leads you up to the area.

Again, I would first check the tube and seal it as it says. Then get the water hose out and do that. This may take a while as water leaks sometimes are very hard to find. But possible.

Hello -

Oh, one last thing............ it looks like you may have some recalls on your vehicle. The dealer may fix these for free. Please contact the dealer service department, give them the VIN number of your car and have them check on these to see if they apply to you.
