Heater core leak in 2002 Jeep Grand Cherokee Ltd

I had a heater core leak in my 2002 Jeep Grand Cherokee limited about 2 months ago. It was leaking water under the car and also I couldn't get the windows to defrost. I got some aluminum stop leak and I no longer have any puddles under the car and the defrost was working fine. My defrost has not been working again. It is blowing air and the air is heating up just fine, but I can't get it to defrost the windows. I had this same problem prior to using the stop leak and it resolved after, but it has started up again but I still don't have a leak under the car. What could be the problem.

    I have a 2002 grand cherokee that will not defog the windows. I do not have a leak that I have seen yet, but I sure hate to completely rip out the dash again, as I have previously done 1 year earlier to repair broken dampers. This sure sounds like the problem of the heater core leaking.

I have 2000 jeep grad cherokee. I have noticed some radiator leak once a while, then was increasing and the light was going on every 3 days or so. So I added STOP LEAK and it did stop, but now the heater is blowing cold air...How can fix this problem? Thank you.

Likely the stopleak is not entirely sealing the leak. Two options: replace the core or put some more stop leak in there. Likely the leak is far less than it had been, causing steam or seepage that is burning off before forming a stream or drip.

Hi there cristina bam! If the core was bad it may have been leaking. Many newer cars on the road these days have a sensor specifically made to monitor the coolant level. If the collant has leaked out there is a very probale chance that the sensor is preventing your Jeep from starting to prevent damage. Add enough fluid to the coolant system to fill the motor block and radiator. If it starts it was the fluid level, if not, there is a greater underlying issue at hand. I really hope that this helps you out and if i was of some assistance please rate my solution. Have a great day!

Windshield fogs up and defroster wont clear it.


You probably have a leak in the heater core which is creating steam in the defrost system. So the heater core most likely needs to be replaced.

Not a bad gasket, as there is no gasket. The heater core has developed a small leak and needs to be replaced or repaired. This is a big job, as the entire dash has to come out of the Jeep. The cost of the part is $77 at autozone, but the labor is several hours at a good shop. We have the procedure and can send it if you would like to do this job yourself. Just let me know.
