it means that if the truck reaches interior temp of 70 or 80 whatever last setting was, the heater continues to blow full blast.

You could turn your auto fan speed down. With 19 minutes on the remote start, temps in the teens outside, temp at 74 on auto, and my auto speed on low; it wasn't a sauna when I hopped in by any means lol. I was thinking about it too, is there a reason the truck idles in v8 and not v4? I'm no mechanic so I'm sure there is an obvious answer. But wouldn't it help on gas to idle like that instead of on all 8? What made me think about it was when I turned the key, I had the Eco gauge on the DIC up, and saw my mpg number start counting down like a stop watch dropping from idling lol.

Mine doesn't get overheated. Fan may be blowing, but the temp control does it's thing.

If that's the case, it clearly isn't working properly. Take it to a dealer.

Well just made my appointment for an oil change/tire rotation and asked about the HVAC system update. Service rep said he would check into it and let me know. I'll find out for sure Wednesday when I take it in. I'll report back here as soon as I know something.

What trim level and which climate control?

Ok I can confirm that this update is real and it works! My HVAC works on remote starts like my 2007 Silverado did, or rather per those specs posted earlier in this thread. I tested it last night. The outside temperature was 43 deg F. I did a remote start and then opened the door and the defrost was blasting. I put the key in the ignition and turned it to "on" and the system reverted to my settings at the time of turning the truck off. I'm beyond happy right now it was so frustrating having to scrape ice off my windshield because I didn't set the defrost properly the night before. I never scraped ice once in my 2007 through 7 years of ownership.

 

The service ticket says: "DIAG PER PIT5240B UPDATED CALIBRATION UPDATE HVAC SOFTWARE FOR REMOTE START OPERATION 99E46."

Did you initially just ask for the HVAC update or give details that with remote start the defroster wasn't blowing? I want mine to perform like yours.

Complain that it's not working like you want it to.

 

Basically I was completely straight with my service rep, explained how it's working and how it's not like my old truck but how it is technically working per the manual but I don't like it and heard from reading on the Internet that there was a production change and might be an update. He wasn't sure if it was a simple software update at the time or not so he asked "are you complaining? Because if you're complaining and there's an update I won't have to charge you." I got the hint so I said yes I'm complaining that on a remote start, my truck doesn't automatically adjust the HVAC settings according to outside temperatures like my GMT900 truck did. Being that it was a simple update I don't think there would be a charge either way. I think he was just making sure I had a real complaint(which I did) and wasn't simply asking for an upgrade if that makes sense.

My March 2014 built truck works exactly as stated in the #2 post for its build date. I have no complaints about it.

Yeah mine was built in September 2013. Sometime between when my truck was built and when yours was built, there was a production change. My truck has basically been updated to function like yours.

Yup I have the early build 2014 and was PO when I tried the remote start and the a/c or heat did not come on (unlike the 07 and 11) and older trucks did, there was posts about the "big step backwards" by GM on the remote start and heater/ac. I realized it when only running the vent on a cool day here in the morning but later that day it got up to 101 degrees remote start the truck go out 5 mins later and vent blowing nice hot air!!!

 

I have had my truck in for numerous warranty items and they have done all sorts or updates and "reflash" they never told me about it and I am always forgettting to preset the climate controls before shutting the truck off but I noticed this winter when I remote start on "cool days" we don't have cold days here that when I went out the defroster was on high and blowing hot air (which was neat) and now as we are heading into "hell" temps if I only had the climate control on vent or not even on when I remote start the truck it is blowing cold air on high until I turn the key then it goes into whatever setting I had it on (same in the winter) so that is a HUGE improvement over the original climate control/remote start functions.

 

The only thing I have not figured out as we never had any real frost type days is if the outside mirrors and rear window defroster come on in colder temps or if the seat heaters automatically activate (like the 07 and 11 and older trucks did) I am guessing it does not happen so if on a frosty morning at least the truck is warm even if I still have to sit there for minutes and manually activate the outside mirrors and rear window defogger?

 

Now if I can get the dang a/c to stop switching to re-circulate mode all the time!! I run my a/c in manual mode not auto and have it set to "outside air" and it continually switches from outside air to re-circulate mode and when it does it it does not show it either on the lighted re-circ button or on the LCD screen still shows it in "outside air" mode so I have to hit the recirculate switch on and off to get it to go back to pulling outside air!!! dealer has not been able to figure it out yet and when I had a 2015 loaner truck when my truck was in for two days of warranty work the 2015 did the same thing!! drives me nuts

^rear window defroster and heated mirrors should activate automatically on a remote start whether you have the updated HVAC software or not.

      Not true! I have been runing them since 2006 F250! suspension component that works as a sway bar, a traction bar, and a helper spring points directly to the RoadActive Suspension (RAS) kit. Works as a sway bar, a traction bar, and a helper spring.

      OCI, not when but why?

      By Grumpy Bear · Posted

      Here's a starter kit:    CC Jensen, a Danish oil testing Concern gives us the following guidelines:   ISO 14/12/10 Very Clean Oil ISO 16/14/11 Clean Oil ISO 17/15/12 Lightly Contaminated ISO 19/17/14 New Oil ISO 22/20/17 Very Contaminated and not suitable for any service.   In addition CC Jensen gives a table showing how engine life is increased by cleaning up the oil. For example cleaning the oil from 19/17/14 to 13/11/8 will extend motor life by a factor of 6X.   But even cleaning it two “Life Extension Classes” will double motor life. So perhaps giving those classes would be useful:   21/19/16 20/18/15 19/17/14 18/16/13 17/15/12 16/14/11 15/13/10 14/12/9 13/11/8   *************************************   https://testoil.com/program-management/setting-iso-cleanliness-targets/   Third paragraph from the bottom will give a starting point.    Your next question should be, okay 10um at what Beta ratio and the answer is in the graph Beta 75.   Then the next question is what is your chosen filters profile? (Purolator PL series below) The red dot is Beta 75. This was the information I obtained from MANN a few years ago. So the best filters, Purolator One, AMSOIL EA, FRAM Ultra, Royal Purple, Bosch Premium should get a doubling engine life over filters like Purolator L, any service filter from any quick lube, WIX, NAPA, STP, Mobil 1, Purolator BOSS.    And as noted by CC Jensen a 2-5 micron @ Beta 200 bypass system has the capability of a six fold improvement. AMSOIL has such a system as does Donaldson.       Now having said all that testing is the touchstone. Test the oil NEW and test it with your chosen filter. Then test over milage. Do the work, get the result. But understand this in NOT absolute BECAUSE this is one factor in isolation.   Example:    A valve spring supplier can state that with cam X and a valve train of Y grams the valves will not float to 7K rpm. is that true if the builder choose a system 20 grams over limit? Common sense must be used and limits understood.

      It varies a ton around me. Some places are still at $5.00 or higher and others are way down into the $4's.   Offroad diesel was $4.02 at the one station I passed today.

      2027 Chevrolet Silverado: Official Discussion

      By Hdwrguy · Posted

      So after reading the reveal from Chevrolet, I kept asking myself...why did the trim levels change?   Here are the official ones:   Work Truck (WT): The quintessential fleet truck, built with durable, easy-to-clean interiors for commercial or utilitarian use. Custom: A stylish, road-oriented trim that adds a more refined appearance, standard dual exhaust, and modern exterior styling. Custom Trail Boss: An entry-level off-roader featuring a 2-inch factory suspension lift and 34-inch mud-terrain tires on a budget. Silverado: Serving as the new base consumer truck (replacing the previous LT trim), it comes standard with the Z71 off-road package when equipped with 4WD. Trail Boss: Steps up the off-road hardware with the 2-inch lift, 34-inch tires, monotube shocks, an exclusive off-road hood, and more premium interior options. ZR2: The flagship off-roader. It boasts 35-inch mud-terrain tires, Multimatic DSSV dampers, front and rear electronic lockers, forged carbon-fiber interior accents, and an available hardcore Bison Edition (co-developed with AEV). High Country: The pinnacle of luxury. It replaces bright chrome with modern satin chrome, 22-inch wheels, premium leather, real wood interior trim, a panoramic sunroof, and an exclusive front-passenger touchscreen. As others have stated, why would you want a Silverado - 'Silverado' - wth?? LT needs to remain!!!   Also, there will no longer be a dedicated Z71 model.  All 4x4 trucks will have the Z71 package. Carplay is also something that cannot be removed.  Hopefully it will remain.     I am excited about the 5.7L V8 (350 C.I.D.)  Old school Chevy power.  My only concern is whatever version of AFM/DFM cylinder deactivation.  Too bad that isn't an option a buyer can choose to have or not.   I will definitely be stopping by my local dealership when these trucks start showing up.
