I have a 2015 Chevy Silverado 1500 LTZ Z71 with the 5.3L V8 and over the past month I’ve had to add a bottle of AC Pro every week for a month now because it would blow cold for a day or two then hot again. Well last night I added a bottle and it was blowing cold and still is blowing cold today but now it sounds like my fan won’t shut off. Any suggestions on too why the fan won’t shut off now ?

Fan not shutting off means you have too much refrigerant in the system. 

 

It could be as simple as a Schrader valve or something more serious like a condenser or compressor leak.

 

I'd take it to a professional to have it checked for leaks.  

 

You could also use a AC leak detector kit with UV dye at home and check for leaks yourself if you like.  However, with the high pressure and how much refrigerant you've added, I'd say there is a good chance is won't be a cheap repair.  Likely looking around $1200-$1700.

Refrigerant does wear out or go away. Better (and a lot less expensive in the long run) to do a proper repair.

Imho you should take it into a trusted shop. I own a 2016 Chev Silverado 4 × 4 LT True North edition w/ the 5.3L. I have babied it since brand new. I just took it into my local GM dealer for servicing after noticing the A/C had stopped blowing cold...turns out the A/C condensor was leaking due to a 'bad' factory weld and has since leaked out all of the refrigerant completely, leaving the system totally 'dry'.

It took almost 5 years for the weld to give out lol. That being said, I still have 2.5 years on the extended GM B to B factory warranty, so 100% of the parts and labour are covered on the installation, fill, and test of the new A/C condensor & system.

🤘😎🤘

I've read numerous threads online stating that GM have had issues with the 2014 - 2018 model years of A/C condensors leaking, due to said 'bad' factory welds.

Hopefully this helps, and with any luck (if you have the +2 year extended warranty) you'll be able to 'gitter done for next to nothing at your local GM dealership. 

Happy trails & good luck 🛻

You have a small leak somewhere. Too small to see freon bubbling where the leak is. While you still have pressure in your system. Get a bottle of water and soap mixture and sprays on your AC line, condenser and all AC connectors. Hopefully you can fine the leak. 

 

Sounds like a seal/o-ring is bad. Did you replace any AC parts recently?

I also have a small leak on my 2015 Sierra A/C ....  doing research, found Class Action against GM for same. I am going to call them after the holiday.....   Crazy,  2015 GMC has a documented Radiator leak and A/C problem. Poorly made truck.

If you don't like a vehicle/manufacturer,  it's simple, you moved on. 

 

Honda dealer near me tried to pull a fast one on me. The alternator bearing had gone out and started making noise. I had additional ground wires connected to the engine block for better grounds (all my lights would dim when stepping on gas). Well because I had additional ground wires. It causing a high flex of power to flow through my car which in return shoot out the bearing inside the alternator (this is what the customer advisor claimed). I stated my case for additional ground wires, he couldn't prove his case, it ended up being cover by warranties. Guess what I did? I traded the Hoe-da and will never recommend anyone to buy a Hoe-da. Learn and move on.

      5 Best Slide Down Gameplay Tips! 

      By lanaderay · Posted

      Are you playing Slide Down endlessly but your score is still low? Are you constantly crashing into obstacles as the game speed increases? Don't worry, this article will share 5 invaluable tips to help you master the race and impress your friends. Golden Rules 1. Look one step further. The mistake of 90% of new players is only staring at their character. The secret of experts is to look towards the top of the screen (where the slide is about to appear). This gives your brain an extra 0.5 - 1 second to process the situation and determine the direction of movement before the obstacle approaches. 2. Use gentle movements; don't swipe too hard. Slide Down is very sensitive. Moving your finger too forcefully or with excessive amplitude will cause your character to be thrown off course or crash into a wall. Practise moving your finger with small, decisive, and precise movements. 3. Don't be greedy for gold in dangerous locations. Gold coins are tempting for buying skins, but life is more important. If you see a gold coin right on the edge of a cliff or next to a spike trap, ignore it. Our goal is a High Score, and your score only increases if you survive. 4. Make the most of Power-ups. During the slide, you'll encounter items like Magnets (attract gold) or Shields (temporary invincibility). Never miss them! Especially the Shield, it's your "get out of jail free card" to help you get through those deadly fast sections. 5. Stay calm when speed peaks. When your score exceeds 500 or 1000, the game speed will be very fast. At this point, don't try to think logically; let your natural reflexes work. Take deep breaths and don't panic. Apply these 5 tips to your next game, and your leaderboard will surely improve dramatically. Good luck climbing the Slide Down leaderboard!

      Why I Recommend a Desiccant Air Dryer for Cleaner, Drier Compressed Air

      By lingyuair · Posted

      If you use compressed air regularly, one problem you cannot ignore is moisture. Water in the air line can cause rust, unstable air pressure, poor tool performance, and even damage to sensitive equipment. That is why I highly recommend using a desiccant air dryer. A desiccant air dryer is designed to remove moisture from compressed air by using drying materials such as activated alumina or molecular sieve. Compared with basic water separators, it can achieve much lower dew points, making it especially useful for applications that require dry and stable air. For workshops, painting systems, pneumatic tools, CNC machines, laser cutting equipment, and industrial production lines, a desiccant air dryer can make a big difference. It helps protect equipment, improve air quality, reduce maintenance costs, and extend the service life of the whole compressed air system. Another advantage is reliability. Many desiccant air dryers are built for continuous operation and can maintain stable drying performance even in demanding environments. For users who care about long-term efficiency and equipment protection, this is a smart investment. When choosing a desiccant air dryer, I suggest paying attention to air flow capacity, working pressure, dew point performance, regeneration method, and maintenance requirements. A good model should match your compressor system and actual air consumption. Overall, if moisture is causing problems in your compressed air system, a desiccant air dryer is definitely worth considering. It is practical, efficient, and highly useful for anyone who needs clean, dry, and reliable compressed air.

      My brand new 2007 Silverado's wax frame was rust from end to end partway through it's SECOND winter here in MA. That stuff is completely useless.

      2027 GMC Sierra: Official Discussion

      By Jsdirt · Posted

      I went another direction after losing a trailer tire, thanks to not being able to access air at ANY of the 5 gas stations and garages I stopped at prior, with a Toyota Tacoma onboard, 50 miles from the Canadian border. They were either out of order, access was blocked, or the hose a few feet too short and I couldn't get any closer without risking damage to someone's property.   https://postimg.cc/gallery/X5QJ55w

      I took a 12 second video on my iphone but the file is too big to upload. I will have to figure out how to extract the audio or just do another start with an audio recording.
