Is there a definite period of time where these trucks were affected? I have a 2016 that's about a year and a few months old and has 28k. No issues so far but I really don't want to have to deal with my ac dying.

The sign is either a "GMC" or bow tie on your grill.

If I ever got a non-GM truck, the Power Wagon would be my first choice. Probably the most practically configured vehicle ever.

Hello guys, I have a 2016 GMC Sierra crew cab. I was just wondering when the bracket that is suppose to fix these leaks was added? Do I need to see about adding one to my truck?

Knightfall,

 

You are going to hit the issue, it might be in a few days, weeks, or a few years from now. My 2016 hit it less than a year with about 1000 miles on it. The good thing for you is you have time until your warranty expires. GM MUST issue a recall. If they don't, the AGs of multiple states will force them to issue one.

Soectaculous, thanks for the advice. My co-worker and I were messing with our subs and ended up opening the hoods. I Remembered what you suggested and I checked...bb015ce54b07272be63494b3d39b0152.jpg514f3be1cadc4fefbdae367249b8958f.jpg8713fe4b86c4a27458a677a419850e98.jpg6182cec622a2b63e06b7e3144bba9b96.jpg

 

Time to start shopping for a new condenser. :/

And here's roof that it is a leak. I had put UV dye in the system the first time I recharged it. 8bb9307aace93f4c92471b84f28b5b31.jpg

This is what my truck has been doing for the past month. I refuse to drive it with no AC. It will be sitting like this for probably another 2-3 months until the re-designed AC condenser comes in. By then it'll be fall so I won't care about AC.

What does the accumulator/dryer look like on these trucks? Is there an orifice tube? I'm just trying to get the parts together for the condenser replacement. Also, how much oil do I have to add to the system?

You'll probably be surprised as I was, but the dryer is integrated directly into the condenser. It's the cylindrical header on the driver's side. New condenser already has fresh dessicant installed from factory.

 

As for oil I can't recall, but it's tiny. Like 3.4oz or something.

It's not a precise science. Put 2 oz in for a new condenser and you'll be fine. Another 1.5 oz for new lines.

 

The orifice is in the block where the lines attach at the firewall.

      Gas Prices

      I understand that. The price is what it is, though. The price is what oil costs today, where our choices have led us, where supply is, and where demand is, in the market that is. Speculation is for futures, what we think the price will be, but with incomplete information at the time the price is forecast. I know you know this, but you appear to be intent on making a secondary point here about what you think the market could or should be, if only other choices.   In 1975 it became illegal to export US Crude. I'm conflicted on what the best answer is. Free markets allow export in pursuit of profit. But there is also a lot to gain by producing and consuming our own oil here. How do you reconcile it?

      That sir is a choice. And even if it were not for all the reasons stated, this disruption has zero to do with the reality of the actual logistics and everything to do with the greed of SPECULATION. Spot price is irrelevant to reality.

      What I think you're saying is there is supply here at home, and in Venezuela, and we could ease pricing if only it were favorable to do so.   Well, yes?   But that's not the current market. Supply isn't what could someday exist, if only, it's what producers are willing to produce and sell at a certain price point.   The national price of single family homes would come way down if we'd just slap together a few million homes this summer.   RAM and GPUs would get a lot cheaper if we just set up some factories to produce a bunch more and stopped using it to build out AI data centers.

      The turn signal/multifunction switch is faulty.  I've seen a few of these go bad at work.
