A/C Problems - Leak at Evaporator Core & Condensor

Took my '02 GC v8 to a garage today to get the a/c looked at. Starting last summer it wouldn't cool, so I limped along refilling it with a can of refrigerant. Now that it's hot again, the refrigerant will not last but 5 minutes and it's out.

The guy at the garage says I have a leak at my evaporator core and at the condensor. He says he can't do the work because of taking out the dash.

Looks like I've got to go somewhere else.

Anyone have a ballpark of what I might be looking at cost-wise?

Last I had had it roughly quoted was about a 600-800 dollar job at a shop....but this was also the same shop that made my A/C worse than when I brought it in...SO maybe that is not a perfect figure, but I know that It is never a cheap fix.

The Problem with the A/C is its a Rabbit chase. you could fix everything and the last thing you have to replace is the problem.

Has anything else on your A/C been worked on before?

It'll be at least $1,000. Taking apart the dash is expensive. It's not too hard to do, just time consuming.

Nothing on my A/C has been worked on. Just me filling it with it 134a.

The guy at the garage said they could tell the leak was coming from the condensor and the evaporator core.

i've fixed several things on my jeep, but i've never removed the entire dash.

what is so time consuming about it? are there instructions anywhere online that might could help me? I'm not opposed to spending my whole weekend working on it if it will prevent me from having to pay $1000.

I took mine to a local dealer with a new "sniffer" device and they told me it was going to be $1,500. The evaporator, condenser all needed to be replaced. What are the odds of both needing to be replaced. I decided to drive a little farther to a friend who works on Jeeps and he said it was just the evaporator in the dash that needed to be replaced. It is an all day job for someone who is experienced at it. I think it cost me $700 for a new evaporator and labor. This is a good one to rob you of money. I think my first dealer was looking to pay off their new freon sniffer device. :-) A shot of red dye and looking in the right places solved the problem.

It's kind of weird to hear them say "evaporator & condenser" seeing as how one is under the dash and the other is attached to the radiator...if you have an evap core leak, do a search here and you'll find lots of help on how to do it yourself. I did mine, it wasn't that hard just takes a while and you have to take your time. But don't put anymore freon in it until you fix it because if it's the evap core it's leaking freon into the cab and that stuff is dangerous....

I took mine to pep boys and they told me 800 to fix it. Yea right!! I brought mine home and did it myself, but i do see why they charge so much. That dash removal deal isnt no joke. Just finished tonight total cost $90. Also a good way to tell if your evaporator is bad, you said yours leaked out in 5 min, so did mine and there was a god awful smell that came from the vents. When i got the evaporator out there was about a half pound of mold and mildew built up in the bottom of the housing. So if it stinks, EVAP

Isn't it possible that I have a leak in both places???

What's weird is that after they charged it with freon to test it, it has held for a week. It's working okay. There is obviously something noticeably running under my hood now that wasn't in the past. I can slightly hear and it feel it running when my foot is on the pedals. It's a light humming sound and slight vibrating feel. What the hell could that be?



I have decided to try to tackle the evaporator core this weekend. I already have the replacement part. Two questions:

1) Can anyone tell me what tools I will need other than a Phillips screwdriver?

2) While I have the dash off, what else should I replace? heater core???

If it's only making the noise and vibration while the compressor cluch is engaged, it's likely your compressor is on the way out. With the leak that you've got, you've been losing not only the R134a, but the compressor oil too. It won't run long like that.

It is possible to have leaks in both places, just not probable, and to hear it phrased like that Evaporator & Condenser, just sounds funny because they are on opposite ends of the engine compartment, not together like say, evap core and heater core. Heater core is a good idea to replace if you're in there already, it costs about 80 buckaroos I think, and you won't have to worry about tearing the dash out again if it starts leaking.

Uhh, yeah. About the tools...it's a good idea to have a cordless screwdriver or your forearms are going to get really tired because there are about a million screws in that dash. You will need an A/C hose disconnecting tool (available at any parts store cheap) You really should replace the accumulator as well since you're going to crack open the system. You also will have to disconnect the heater hoses in the engine compartment (I had to cut mine off because they were stuck). So that requires either a flathead screwdriver or a small socket (9mm I think). Or a hose clamp tool depending on what type of clamps are currently on the hoses. Aside from that just kinda go along and see what you need as you come to it. And feel free to ask us questions frequently as many of us here have done that job and we can help you. If you get stuck, ask...

Oh, and it's a good idea if it still has freon, to have it evacuated first, or else you may get a face full of freon when you open the lines...
