A/C Compressor Works With The Scanner, But it's Still Not Cold!! 

Im very thankful for what I've learned from this dude

When I have a leak that is not easily found, I will put in new shrader valves before recharging. They are cheap, less than $2 each in my area, and are one of the most common sources of leaks.

They used a leak detector on my jeep commander, the sniffer if you will, and found out it's my evaporator. $$$ to fix, so I haven't done it yet. I was thinking about doing it myself, but pulling the dash is not so easy in that thing. I wish I was near you, because I want to be sure to have a honest mechanic do it. Good video, keep us apprised.

Keep safety glasses on I had a discharge hose rupture and almost blinded me. 50 year refrigeration mechanic. Retired.

If the system is completely discharged of refrigerant what else can you do? He did exactly what you describe, you have to have something to inject the dye into. Maybe he should have just run it in the parking lot for a few hours so the leak can evidence itself, but sending it home with his instructions is a reasonable option. I know there are other methods, like pressurizing the system with nitrogen, but his solution will work

Did you change the schrader valves ? I know that maybe a stupid question but I have seen that happen before. Cheers.

Check where the llocating tabs are on the condenser they always break and leak

Had my seep out of the valve or a long period of time they didn’t tighten the valve down enough

Where did the aircon gas go to? Usually, when the air con is not switched on or used in winter, the seals dry out. A dry seal will not seal. That is why i turn on my air con every day for 15 minutes even in winter.

Interesting

Seems likely that the seals have failed and that's if the problem was slowly progressing.

Why not use your black lit now??

Wouldn’t the pressure switch shut down the system when the “leak” reduces the refrigerant volume to a certain degree? At that point the remaining refrigerant would be under no pressure and would not continue to leak out. My guess is someone evacuated the system and for some weird reason didn’t recharge

Check schrader valves..

I wonder if the schrader valves leaked slowly over time? And when you recharged the system they got reseated?

Nice job Kenny, hopefully it was just nothing in the system.

Need 30 min videos.

Why not pull a vacuum on the system and see if it holds?

It's a Ford 😮😂

You can never get the whole story I know I work on a/c all summer

Watching Ray repair He pretty much changes the schrader valve anytime he touches an a/c with a leak 99% of the time that Is the cause of the leaks He shows the Schrader valves and they are usually trash

If the scanner can bypass the low pressure switch, there is a problem.

This is 100% the improper way to do this Diag! You put dye in it and run the system and find the leak. I'm actually disappointed. Check with a Black light you will find it. I had a truck come in to the dealership and it was at 7 different shops from California to Michigan. We found the leak! took 35 minutes because we needed heat in the a/c system to expand the components. It was a very very small leak. It ended up being a weld on the condenser had a pin hole in it. The way you did this is a poor practice. Not only did you charge it knowing it had a leak i'm sure they were charged for a A/c Re-charge and will again after you find and fix the leak. Love your video's Kenny but this one i was not happy with how you handled it.

Your volume is low sometimes. I really have to hold phone to my ear to hear you.

Your videos aren't loud enough. Can't hardly hear you talking.
