SOLID video. Perfectly broken down, not skipping over things. Really appreciate your efforts man!

[@purgasound]

Great video. Just checked my 2015 Silverado 1500 with a 5.3 and found the leak in the exact same spot. Thanks for the tip!

[@bryanbrickson1573]

There is dye in the system from the factory. Adding refrigerant brings it back into circulation. A system is always vacuumed before filling if empty. You could vacuum the low side to suck the dye in the high side. That body style always leaks in that same place. Put the can upside down and regulate it with the low side of the manifold. Just open it a small amount and the whole can will go in in a minute. You are evaporating the refrigerant in the can causing it to get cold and lose pressure. Upside down it evaporates outside the can and the temperature and pressure in the can remain much higher

[@ydoyouthink]

your comments are the most common sense for this video

[@robmar1831]

Thanks for the tip about dye in system from factory. Put a UV light on that weld and immediately saw the problem.

[@6rowlettes]

Nicely done. Thanks for taking the time to demonstrate how to troubleshoot and confirm the leaking part before diving into replacement.

[@Jfoy42]

So this video REALLY helped me out alot!!! I was racking my brain trying to figure out where the leak was coming from.... I charged the system and put in some dye using this stupid injector tool I got from a part store (I didn't realize you could put the dye into the gage set before I watched this video)😅 then charged the system and sure enough BOTH the top and middle weld points were faulty. 😳😱 I'll be replacing the condenser this weekend and I'll also use your idea to reinforce it with some JB weld to better assure this won't happen again. I'm hoping this was the entirety of the issue with my truck. 🤞 Thanks for the content!! God bless! 🙌

[@CaptainKenny696]

Thanks. Did the test yesterday and it was leaking exactly where you show. I appreciate it.

[@michaelbush2639]

cool basics, but you can hook up shop air to the yellow line on the manifold gauge and charge the system with air to find the leak since you had already determined there was no system pressure. This way you don't waste refrigerant or die.

[@Steve-yk8iq]

I appreciate this video and your concise way of speaking informatively. Mine is a 2007 actually so I'm going to do a little more digging for info but this helps a lot. and it's 28 days above 110 in Phoenix right now so we need our AC lol!

[@MrTalmaguer]

Dang you helped me out. Checked the condenser and yup without the UV light… very noticeable the leak on that same tack weld 😭😭

[@ceebfwmmuas1114]

Thanks BMS! I refilled my truck with refrigerant and it lasted about a day. The following day, my truck was blowing hot air again. I'm pretty sure I have the same problem. I will double check, but thanks for a great video.

[@anthonycostill8654]

Was there a leak in your condenser

[@xThat1dude]

Sweet! After searching and searching I found this. Only video that shows and explains the actual problem

[@earlysquad1098]

Thank You for this Video. I have a 2015 Suburban and the AC has stopped working. The dealer has already replaced the condenser once as a recall and It looks like they will be doing it again. Thanks again for the informative video. 🇺🇸

[@guylongley1573]

Yep Heartburn of America. Great video just remember to vacuum the crap out of it when you're done to get all the moisture out. 🥶

[@BoostedMotorsports]

Guy Longley agreed! I didn’t hook up my vacuum pump for this since we are taking the condenser out and only put enough in to find the leak! I’ll post the repair video next 💪

[@jasont3913]

Excellent video and troubleshooting. Thanks very much for providing it, and for being so clear in your explanations. More people should follow your style. Kudos!

[@Limitlessmaint]

Thanks a lot, your video helped me a lot, that was exactly what was causing the problem on my truck

[@frankgonz31]

This are super easy things to diagnose, the why is blowing warm air while good pressures or compressor working ,good pressures but no cooling. Those are the bomb 💣

[@thomasnielsen7466]

quite common means planned obsolesce, the supplier will not improve the 3 point welding, that is how they make their money, if it last past the warranty, and break again, the product is perfect

[@WilliamWeeksKC]

Thank you for the heads up on the location. I can tell I have the same leak at this weld.

[@timothyvaughan7974]

My 2017 silverado just stopped cooling all of a sudden so I wonder if this is my problem . I at least know where to look first so thank you for the vid!

[@charlenewilliams8131]

There should be a recall on it.

[@jasonbennefield4695]

I think I have the same issue with my 2016 Yukon, but the compressor does not come on. Can I add refrigerant without the clutch on or would you try jumping the pressure switch to add it?

[@jesusloera5294]

I dont know for sure but my compressor would not come on and then when I added the refrigerant, the clutch started spinning so there may be a temperature indicator that engages the clutch

[@givawnvasser6520]

Did anyone try to do the relay or sensor bypass? I've tried I think correctly on the sensor and the fuse can't get it to engage and don't wanna buy freon to let it leak out haha

[@TejasToolMan]

Great video! Cant live with no ac in summer time lol. Easy way to find the leak if you can't see the obvious ones air it up with compressed air 45lbs, spray bottle soapy water an spray all connections. Fixed my 03 Ram in one weekend.

[@BoostedMotorsports]

Tell me about it! I’ve been driving the Dakota all summer with no A/C and it’s been over 100 for weeks I think I’m putting the A/C back in and I’ll figure out how to fit a smaller intercooler for the supercharger later it’s brutal without it

[@TejasToolMan]

@@BoostedMotorsports you can use and old kitchen refrigerator's motor pump and it's a bad @$$ vacuum pump for doing ac on the cheap and get that solid -30 vacuum

[@BoostedMotorsports]

I have an ac vacuum pump! Just didn’t bother using it since the condenser has to come out. We just charged it quick to find the leak 💪

[@marvinbrock960]

Can you tig up the leak on the AC condenser?

[@danieljenkins4791]

Thought you were supposed to use R-1234yf in these trucks?

[@bigalshouse3033]

Hey I just saw your videos very handy do you happen to have a recall Link or website I have a 2015 Chevy Silverado

[@JG-sq1bs]

I've got a 17 and GM says no recall.

[@JosephWolf]

My 2018 uses something different that 134. Can't recall what it's called.

[@Krusty-kl5ej]

Thank you sir for that concise diagnosis. I likely have the same problem in my 2014 Silverado, but no tools to fix that leak. At least I can undertake an economic way to determine where the leak is, hopefully saving time and money at the repair shop. I shop I spoke to already provided a horrible quote to replace the entire system without ever referring to this diagnosis. Watch out for those pirates.

[@kodiakriver6297]

That is why it's important, to have a mesh system front area , once you have a simple stone or gravel rocks , rubbing against radiator and liquid pips, it's a matter of time tiking before a leaks.....

[@jerrywilson4795]

GM is in a class action suit but dealer has NO recall on this ?

[@NobodyGotTimeForThat]

I can see oil or something next to that weld on mine and it looks a bit corroded where the other welds below it still look normal. Is this a good indicator that it has cracked..? 2015 Silverado 111k miles

[@nighthawkj30A4]

GM had a TSB with a bracket that is install on the Ac lines. But i think it only applied to condensers. That have not cracked yet.

[@ryanbarraza7426]

Thanks for the video.Have the exact same leak,in the exact area.I put about 6 oz of freon in to start the clutch and find the leak.Was 6 oz still not enough to push any cold air through? It was still hot? Also, do you think I can use some JB Weld on that tack weld leak?

[@bryanpope3106]

I was thinking the same jb thing did it work

[@jsagil6785]

I replaced my condenser the last day of December 2021, got it recharged at a mechanic’s, it is now July and the AC is blowing hot again. There doesn’t seem to be a leak on the new condenser. Any idea what it could be?

[@cademmo]

I need help PLEASE my 14 Silverado air is intermediate. Sometimes it works great sometimes it doesn’t. I have replaced the high pressure switch and checked the pressure just on the low side with a simple can and gauge from advanced. The pressure maintains around 40psi according to the gauge. Any tips would be GREATLY APPRECIATED where to go to next.

[@WastelandRonnin]

Any tips on what else to fix. Ive replaced the actuator door motor, charged the ac, ac pump turns on and bled some coolant atill nothing

[@jeffbohannon8550]

With the condenser leaking like that would that be a cause why the radiator fans are always on full blast when driving the truck?

[@MichaelShirley-nl5pe]

Temperature sensor is bad will cause the fans to run continuously

[@12guagejulz]

2015 gmc sierra same issue , will be taking it dealer

[@juanlamas5605]

You said compressor was not engaging. Are you saying it's not engaging because there was no r32. Cuz mine is not engaging either.

[@lNerdsNamedMicah]

No freon...no clutch.

[@NobodyGotTimeForThat]

There's a pressure switch interlocked with the clutch so the compressor doesn't burn out from running without refrigerant.

On my 2018 Tahoe, the ac and heat failed, would shut off after about 20 minutes of driving. Shop said it was because the temp outside.. so replaced actuators, evaporator core. So now soo cold it freezes and closes vents, same as before. Shutting off ac opens vents, fan blows whole time too. And no heat until after 77, vents close again after while. Then heat at max stays on, ac at max stays on, blower set to max. There is no middle.. any help appreciated.

@@michaelcox86 YES! apparently my Tahoe, and potentially your Suburban takes a different refrigerant called R-1234YF. You can buy a recharge kit at Advanced Auto parts.

They recharged my AC, and it blew cold the rest of the day. i parked it overnight and when I got in it in the morning the air was warm.
