Remote Start Settings

Isriam · January 16, 2015

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.

I guess the explains why mine wasn't super hot either, must have kept it in the 70s.

ive jumped in after it was warm and remote started and its like 80 in the cab. i have to actually put the keys in to turn the heat off.

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
