HOW TO DIAGNOSE | 2014-2019 A/C FAILURE on SILVERADO | SIERRA | TAHOE | SUBURBAN

We show how to diagnose your A/C not blowing cold air on your 2014-2019 chevrolet Silverado Sierra tahoe or suburban as we go step by step to show how to narrow down why your ac is not working and how to figure out why your ac is not cold in your truck or suv. We first discuss the common failure on these trucks is the ac condenser and the welds on the end are prone to leaking freon or refrigerant from the system causing the ac to completely stop working. This was a recall from GM on these models and years and unfortunately many did not get the recall even though the problem was the same on all trucks and suv during these years. We show where to look and how to use uv dye in the ac system and how to see exactly where the leak is coming from or where you can look on your truck before you spend your hard earned money!

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

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! 🙌

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!

Thank you sir for that concise diagnosis. I likely have the same problem in my 2014 Silverado, but no tools to fix that leak.

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.

[@hectorhernandez9892]

I have a 2015 GMC Sierra 1500 and AC not blowing cold air. Can I take it in for the recall?

[@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.

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.

@@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

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

[@elliottmorris6439]

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.

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

[@eltejano4439]

How did you find out which freon your truck uses? (134a or 1234yf)

[@user-fp7ee2mk3c]

I'd put the gauges on the high and low. If you only have a can fill with gauge then if you don't see 50-55psi on a day like today in Missouri you don't have enough r134a.. not sure when GM switched or if they switched like Ram to the r1234x or not. So if you have good pressure nd you still don't have temp in the cabin check your cabin air filter or listen for a clicking sound that's telltale of the blender actuator that controls the door in the box that determines whether you have heat or AC (what temperature is allowed in the cabin), if you have pressure and it's not one of those things the control heads on GMs have been as big of a disaster as another brand I'm not mentioning.. probably a bigger disaster. If you have 4.5 volts back feeding at the ground near the condenser you need to check for stray voltages at the power distribution box.. next time get the W/T or a custom LoL. If you don't have the right pressure you need to find out if you have a slow leak or a fast one. If it takes a year or longer to leak out pressure I'd probably try some sealer charge and if it's a quick leak it's probably just minor like the low pressure switch cutout at the accumulator. I have ran GM systems with a bad high pressure switch by just bypassing it... but you'd want to know your pressure really well before you went that route and you'd have to know what you're up against there. If you do the latter make sure you keep that condenser clear of debris, in the least. In the case of the GM I ran without the high pressure switch I knew the system had been flushed and I knew it had a new compressor, condenser, accumulator, and orifice tube. If you don't know the internal condition of any of that I probably wouldn't do that for any indeterminate length of time.
