I have a 2015 Yukon that had the air conditioning stop working. It normally blows hot air, but every now and then it will randomly work great. I added some freon yesterday and the compressor kicked on and everything was working good, but as soon as I turned the rear air on high it started blowing warm again and the compressor stopped cycling. I thought maybe it the rear air thing was just a coincidence and it had leaked all the freon out immediately, but now (a day later) I'm driving and it's been working for a few hours now. Any ideas? Thanks in advance guys.

FYI:  Had a 2005 XL, had leak between front and rear, $1500+ to find leak in rear, $500+ to replace rear compressor, less than $500 to cut off rear A/C, which is what I had done.  If I did want it fixed I would have started with replacing rear compressor.  Suggest having a radiator-A/C shop check it out and suggest options.  Good Luck.

Sounds like you have leaked out just enough to hit the low pressure shut of for your AC clutch. When you added 134a it gave you enough refrigerant to keep the pressure high enough to run the front ac. When the back was turned on the pressure dropped and the clutch cuts out. I suggest you add some leak detector and find the source of your loss. My guess is upper driver side condenser (can be seen through the grill), or lower passenger side condenser where the lines attach (bracket was later added due to failures), or near the service ports by the passenger side of the engine (bracket added here later due to failures). Lucky you, 2015 still uses R134a which is cheap. Mine is running the new expensive R1234yf. 
 

GM has a warranty extension they call “special coverage” for condenser failures if your Yukon has less than 75k mi and the VIN number is covered. Has to be the leak at the driver side of the condenser.

      Scan Tool Recommendation

      By PunchT37 · Posted

      I just bought this. A minimum for me but, I don`t work anymore and don`t want the heavy update costs of the higher end tools. You would have to make money with them.   https://www.topdon.us/collections/diagnostic-tools/products/artidiag-pro   Even this tool has a $250.00 update cost after 2 years.

      Scan Tool Recommendation

      I have an Autel, works great for what it is. Can't do some specific things because you need say the GM tool, VCDS for Audi/Volkswagon and others of course. But those times are few and far between for me.   The other tool I'd like to try one day is the new Topdon scan tools. Seen several video's on them and many youtube people review them.    I've never subscribed for updates or payed to do that stuff on my Autel, so I'm sure I'm missing out on some of the updates but I'm fine with that for now.

      I am in the market for a bidirectional scan tool so was hoping someone can help point me in the right direction. There are so many options out there it is hard to narrow down which make/model to choose.   I have always done my own vehicle work so looking to maximize capability with the scanner. Ideal price is $1k or less but would be willing to exceed if it opens up significant benefits.  Currently my 24 2500 is the newest vehicle but also have a few mid to late 2010s Subarus as well.    It seems that the Autel MP900 has a decent amount of features at a reasonable price?

      Silverado 4500-5500-6500 are they still being produced? Would have sold better as GMCs as well

      There was talk over the last couple of years that the contract to build these trucks between GM and International would not be renewed.  International moved production of all their other trucks besides the companion CV model out of the Springfield plant some time ago when they opened their San Antonio plant.  That left Springfield only building the Silverado Medium Duty, International CV Series, and some Express/Savanna long wheelbase cutaways.  International also put the plant up for sale some time ago.  This all answered my earlier question as to why GM and International did nothing with these trucks since they were introduced, as they had basically become a market 'placeholder' with a finite life.    The Silverado Medium Duty/International CV trucks were interesting combination of a GM powertrain, electrical system, and K2XX Silverado cab with an International chassis that was supposedly designed for a step-van type vehicle they never produced.  They were manufactured in International's Springfield plant along with the IH MV series initially.  When first introduced, there was much talk that the Silverado Medium Duty/CV would eventually get a gasoline engine option along with other upgrades and GM and IH would work on a class 6/7 joint venture truck.  This was before VW bought Navistar out, after that happened no more was said.  Draw your own conclusions...   About the time talk started that the GM/IH joint venture was not going to be renewed, rumors started that GM would develop a new line of medium duty trucks themselves.  The story is the new trucks will be part of the next generation HD's due in 2028, and will still feature a 'straight rail' chassis design that the current medium duty has.  GM views this as a desirable feature that differentiates their truck from the competition.  A gasoline engine option is also expected.  As the current Silverado Medium Duty remains in production until September 2026 and there is still a lot of inventory available do not expect any official word for some time.   I believe GM remains committed to their successful partnership with Isuzu, and all the LCF models will still be available from Chevy Commercial dealers.  Isuzu is on the cusp of opening a new large plant in South Carolina and there is also speculation that this may result in new product for both Isuzu and Chevy Commercial dealers.
