All help appreciated thanks. They make dye that you put in through the system and use a black light to find it. Most shops will do it for a relatively low fee. |

This, you could also use a sniffer which detects the leaking refrigerant and beeps louder when you move closer to the source of the leak. |

No no no! Don't ever use those stop leak products. Now a lot of shops wont touch your HVAC system because it has contaminants in it. |

A couple of things:
First, you're fucked. No one will evacuate your system now that you put stop leak in it. It destroys the recovery and recycling machine, and voids the warranty. Everyone I know with a machine (including myself) tests for sealer prior to evacuation. Never, ever, under any circumstances EVER put sealer into an AC system. I don't know how more plainly I can say that. Without pulling a vacuum on the system, you'll never get the air out..........and air is a lousy refrigerant 
Second, dye is the easiest method usually. There are other ways to go about it, but that's the cheapest and easiest for a DIY'er. One thing you might consider is using your eyeballs and looking for oil stains on the condenser, compressor, and lines. If you can get to the evaporator, look at that too. As it is a Chrysler product, and therefore has the worst air conditioning on the planet, I'm putting money on a bad evaporator. Chrysler evaporators are absolute crap. I hate to say this, but with sealer in it, you're either going to have to live with half-assed AC, or replace every single AC component: Compressor, Condenser, Evaporator, Thermal Expansion Valve, Reciver/Dryer, and lines. ETA: One thought......and this is a little less gloomy. If you can find someone with just a vacuum pump with the R134a fittings, you could pull a vacuum on the system yourself, and get the air out. That's probably your only solution at this point..........at least after you find the leak and repair it. |

Also it's almost 20 years old, how long do you expect it to last? The seals, the refrigerant, the compressor, etc? |

It's a fucking Cherokee, you'd spend more on an A/C system overhaul then the jeep itself is worth. If it were me, I'd pull the system out and buy a Non-A/C serp belt for the bulletproof 4.0, then run doorless in the summer  This. I can't wait to pull my doors off this summer.
