You forgot to mention you need to add uv dye into the system through a Schrader valve in order for it to show up with the light and glasses. Adding the dye will not work if your compressor and ac clutch won't engage due to low pressure to circulate the dye through the system. You can bypass the low pressure switch but if you ac clutch and compressor don't engage you'll have to replace those first before you can begin to diagnose a leak

[@DadBradTo5]

This lady is obviously very knowledgeable re Auto AC Systems, BUT, for the novice watching this, she totally "glossed over" HOW to get the UV Dye into the system, AND as a previous commenter noted, if one's system is completely "dry" (no Refrigerant in it whatsoever), and/or its completely inoperative, you CAN'T get any UV Dye into (and thus circulated throughout) the system!! Injecting AIR under pressure into the system (if the UV Dye method can't be performed) is also a way to LISTEN for leaks, as well as by observing, using a bottle of soapy water, and spaying it on the various ac hoses, and related refrigerant-carrying tubes, etc, and looking for the "bubbles". ONCE the leak is located, and repaired, THEN the system must be THOROUGHLY VACUUMED OUT, to remove all moisture. Good video, but inadequate imo, and those watching this would do well to view a number of other related KZbin Vids, in order to get "The Whole Picture"...

[@jasonlecreux1175]

I can agree to an extent about your opening statement of “ac doesn’t go bad”. Refrigerant is hygroscopic, meaning it will absorb moisture, which will contaminate the refrigerant. Your AC system is meant to be serviced (every few years), not so much to replace the refrigerant, but to vacuum the system to boil off that moisture. Also, “Freon” is not used. Freon is a brand name for older gases (R12). You’re not going to find Freon in modern vehicles.

[@adventureoflinkmk2]

Not to mention you have to change the oil in your car anyway, why wouldn't you wanna get an evacuation and recharge to get fresh oil anyway

[@DashCamSerbia]

What misture? It can't enter the sealed system. Even if the refrigerant is leaking, it does not mean the moisture can get it. Refrigerant molecules are much smaller than water molecules. And the system is under pressure, while the moisture in the atmosfere is at the atmosferic pressure, so it can't get in.

[@withgrowinginsanity198]

The style and format of this video is top, thanks

[@TheWorkBench]

Absolutely thank you so much for this video. It certainly helped me to know what the issue is.

[@tedjohnson64]

Nice video! I’m glad you showed two different examples.

[@trippm4036]

Best video I've seen on diagnosing AC system problems.

[@dgax65]

I always learn something from these videos. Thanks.

[@deanbarr5740]

Sue, I have a 2004 F- 250 with 180,000 miles, for almost 19 years old truck I've never had any A/C problems. Never had it charged and thankfully it still blows cold air. That's unheard of but true. I'm the second owner and as far as I know the previous original owner never had any issues the 7 years he owned it. Always enjoy your videos. Very helpful info you share.

[@RakeshPathak-lu8yc]

Old is Gold i have 1999 lexus gs 300 never ac gas leak issues,no rust very quite motor

[@michael184272]

Very interesting and informative video... Thanks for posting..

[@denky28]

Super helpful video, thank you!

[@mpcp27]

Thanks for the video. Can you post a link for the UV light you were using? Any chance you know the uv wavelength ? 395 or 365 nm? Thanks.

[@garnellwalls3721]

Great job, I love the way you do your video. You explain thing very well. thank you,

[@HotRod-wv4vm]

Thanks for the video 👍

[@renerivas3619]

Nice recomendation👏👏

[@emiliog.4432]

Sue is the best.

[@oralreid7714]

Thank you

[@JKBarteezy]

Fantastic video hon!

[@kdeh21803]

This would be great if there wasn't a "Extra" problem.... I have put dye in my system 3 times now and I don't see anywhere it's coming out, and after a few days, the refrigerant is gone from the system..........................

[@knockywigglesworth1909]

Sealed just like a refrigerator but you never drive your refrigerator at 70mph & stop it with a brake.

[@flipdzon]

Hello, I had my 2016 Ford Explorer A/C diagnosed with a rear line leak. They estimated the work would cost $2500-$3000. Is that an accurate or a honest estimation for the job?They evac and recharged the system with dye a week ago. 6 days later, it was blowing hot air again. Thanks

[@kenseagle4169]

Yes good video. Except as mentioned by other people, she left out the whole part of having to inject dye into the system in order to find leak. Pretty important step, seeing as everything she shows you is useless unless there is UV dye in the system.

[@salmanefiautoworkshop2382]

Very good 👍👍👍👍

[@redtobertshateshandles]

I couldn't figure out why I had a drip of coolant under my a/c compressor, but nowhere else. It's not coolant it's a/c stuff. Thanks

[@dustinhankins2153]

Will this work even if your system has no Freon in the system at all?

[@totalannihilation9065]

Great indo. Down I go.

[@ryanh3285]

Does the gas already have dye in it then?

[@joshua12345j]

could you use a black light

[@mrsajal6089]

Mam where your workshop

[@eduardomontanez4661]

You never showed how to add dye!

[@garyslentzii2796]

Also check the drain puddle for dye, might have evaporator leak from inside cabin

[@jasonlecreux1175]

Evaporator

[@garyslentzii2796]

@@jasonlecreux1175 I couldn't think of the name at the time, stupid meds

[@stevenhunt66]

FREON is a brand name of REFRIGERANT... There are many makers of refrigerants.

[@tonistarks2874]

While this video comes out nice and edited, it leaves a lot of info out 🤷🏽..

[@jizchimp]

Freon doesn’t go bad. If it’s not blowing cold it’s be because it has a leak.

[@MikeBrown-ii3pt]

And then, you have people like my brother. You know, the kind of people that will spend $1000 to get the a/c fixed on their 1999 whatever but won't spend $250 for new pads, calipers and rotors when their brakes are grinding! Maybe I'm wrong but, I think brakes are A LOT more important than air conditioning! Don't worry fellow viewers! I spent $250 of MY OWN money and installed new pads, calipers and rotors on his car for him! I didn't touch the a/c system though, that's on him!

[@drewbush6535]

👍

[@RaymondHamby]

I wish my leak was that easy to find. Put dye into the system and can’t find a leak anywhere. I’m afraid it’s my evaporator behind the dash

[@lemmykilmister873]

🤔

[@markkenny5799]

Who still changes their own compressor without retaining the old freon!😀

[@adventureoflinkmk2]

I would, given we don't use freon in cars and we haven't since like 1993 or thereabouts
