A/C System: Need Info.

Hey everybody. I finally turned on the A/C in my Cherokee for the first time since I have owned it. Surprise, it blew out hot air. SOOOOO I bought the recharge kit from autozone and connected to the low port and turned the A/C to full blast and it got cold..... So I thought, coool ..... Well after getting back on the road running my errands, it started to get warm not hot though. I shut it off and rolled down my windows..... After getting too hot for that, I turned it back on and it got cold again then hot again..... I did this all the way to where I had to go... Whenever I turn the car off I can hear a hiss from the front of the car and a very quiet hiss from inside the cabin. I assume that its leaking somewhere but is there a way I can tell what part it is without putting the stupid dye into my system and seeing if its the evap core or the condenser??? Any help appreciated.


I've got a 1/4 tank of gas, a pack of smokes and I don't get paid until next week. Lets go!

Sounds like you may not have put enough refrigerant in. Try another can, because if it leaked out, it would not get cold again, at all.

4x4s are what you make of them, or do with them. No guts - No glory ;')

Dye-type leak detection rarely works on finding evaporator leaks on XJ's. This means you need the services of a pro to at least FIND the leak, even if you want to fix it yourself.


Have a professional shop pull a vacuum on the system and see if it holds vacuum or not. If it does not, then the only SURE FIRE way to find the leak(s) will be with a partial recharge and a "sniffer".

I don't own an XJ any longer, but I still think they are the best of all the Jeep products ever made. My XJ was my favorite vehicle in my 50+ years of driving.
So...I stick around and give advice.
