A/C Freon Loss under dash

I can recharge the system and it leaks out under the dash. Is this the evaporator or a seal. Do the stop leak products work in this type of situation? I will try the dye and black light this weekend.

I have the same problem with my Focus, except it does not leak out that fast. The evaporator coil probably has a hole in it. I took one out of a used car and found a bunch of leaves up against it which precipitated oxidation and its failure. The connections for the coil are just outside of the firewall. If you are thinking about changing the thing yourself, the first thing you need to know is that Ford only sells the whole heater assembly - it costs $525, and that it is a seriously painful operation to get it out. You have to remove the WHOLE dash and more. Good Luck.

How to repair evaporator system in 2004 Saturn ion

I have a car that has a leaky evaporator coil, too. Here's what I have found:

A leaking evaporator coil is usually replaced. On most vehicles, this is a labor intensive job requiring complete dis-assembly of the dashboard to gain access to the coil. Your particular vehicle *may* be different.

Some companies offer products specifically made to seal relatively small leaks in the refrigerant system. Independent reviews that I have read show mixed results and some indicate use of some of these products can cause greater harm to the system. Some manufacturers claim their product along with a system recharge is all that needs to be done. Others require replacement of the filter and dryer so that the air and moisture is able to be completely eradicated from the system, this is because once system has been depressurized due to the leak, air and moisture eventually enter. That air and moisture must be purged before running the system because water can not be compressed and will create issues in the A/C compressor. It is important to note that some refrigerants are marketed with a dye to help locate leaks and even some with a "leak stopper". These products are fine to use. It's the stand-alone leak stopping products that I'm talking about here. You should try the refrigerants with a leak stopped / dye. They can seal small, slow leaks effectively. If you need to recharge annually - that may be the way to go. Large leaks that empty in as little as a couple weeks or a month will probably not be stopped with these products.

For these reasons, I have opted to spend money on replacement of my evaporator coil, rather than risk damaging the entire system with a "stop leak type product". Here's search result page for "stop leak" products that you should review.

Good luck!

Continuous loss of refrigerant in air conditioning system. A/C has been evacuated and tested with dye under pressure but no leaks are found (except my usually excellent mechanic says it might be under the...

Could be the evaporator, rare but possible. Double check the schrader valves on the high and low pressure lines, and the shut off valves on the lines going to and from the condensor, and the condensor itself. (common culprit) Also the front seal on the compressor if leaking will have oily residue all over. No offense but try a different mechanic. Sometimes a new set of eyes works wonders!! Your mechanic won't be offended. If he is, fire him.

with a/c you usually have to replace the part that is leaking.hose,condensor,evaporator.or if its a seal,seal replacement,schrader valve etc.this needs to be done at a shop that does a/c work as the system will need to be evacuated,repaired,vacumed,recharged,proper oil installed and rechecked for leaks,and checked for proper operation.

The front air conditioner on my 2003 dodge grand caravan has a small leak that the dealship says is under the dash. Can I just put a charge on the front unit the back unit blows cold air. Is this...

There is only one system, so your conclusion doesn't make sense. If the front evaporator is leaking, the whole system will lose charge, and the back will not be cooling. Your problem may actually be the front blend door. Recommend you get a second opinon. Evaporator replacement is much more than $300.

Evaporator coil leaking. do i have to remove dash board to replace?

mcdevito75 here, Yes, or a good part of it. But wait, if there is water on the pass. side it may be the drain for the evaporator, in that case look under the evaporator and make sure the rubber drain hose is attached, also use something to un clog it. If it"s the evaporator leaking freon then you"ll have to remove and change or fix the leak, a radiator shop can seal the leaking evaporatoro once out of the car, first you"ll have to drain all the freon from the system.

Leak in a/c system,installed 2 cans freon w/oil & stop leak.Can got cold once putting in temp. insice hot always.

Stop leak, thats great, now its going to cost even more to repair your a/c system. Take to a shop that does a/c and prepare to pay. its going to need a compressor, condenser, evaporator, drier, exp valve and possibly hoses.

Air conditioner not blowing cold after recharge last year

david_simko: based on your description above, it definitely sounds like you have a leak somewhere in your A/C system. If you re-charged your A/C system last year, you should still have plenty of freon (R134-a) coolant in your A/C system. If you are familiar with how the A/C system works on your vehicle, there are two products you can use to help you identify leak in your A/C system. The first is a liquid that you inject into the system. This liquid will come out (in a solid color) in the area(s) of where the leak is accruing. The second device is a electronic freon sniffer. This is a small hand held device with about a 10" antenna on it. This device electronically "sniffs" for freon, and leads you to the area of where freon is leaking. Since you've stated that you re-charged your A/C system last year, and since has degraded from cold air, to warm and now hot air, you will have to (at minimum) partially recharge your A/C system to use one of the two leak detection methods I have mentioned above. PLEASE VOTE FOR THIS REPLY IF YOU HAVE FOUND THIS INFORMATION HELPFUL. Thank you.

No a/c, no freon....2001 dodge ram 2500 diesel 2 wheel drive

It is most likely the evaporator leaking. You'll need to remove the dash panel assembly and the heater housing to gain access. I have replace many Chrysler evaporators in trucks, minivans, and Jeeps to name a few. I hope this helps.

97 buick skylark ac evaporator core what do i need to do to get to it

Did you replace the schrader valves (the thing in the inside of the A/C service fittings, you need a special tool to remove and install them) before you recharged the system? They are notorious for leaking if they are old.

If you did not, replace those and try again, if it leaks out again with no evidence you most likely have a bad evap core.

And yes, it's a pain in the ****, plan on it taking a 30 pack of bud light and a weekend to do, or one day and a 12 pack if you are good. Just start taking the dash apart, and may the force be with you. It will be behind the glove box
