Question for all, when you remote start in the winter months, is there a trick to get the heater gushing or to come on? I ask because, I have started in 30 degree weather and then came out to the truck 10 minutes later and the only thing on is the heated seats and steering wheel. Dealership says that all GMC come that way.

I find it hard to believe that a 80K vehicle has the truck cooled on a 90 degree day with remote start but not heated on a 30 degree morning.

Thank,

Wes
 

I don't know what year your truck is, on the pre refresh, the center stack has those settings, you can also get to them from the mygmc app.

You can set the max fan speed, but not the temp, it defaults to high, but 10 minutes isn't going to have heat yet if the block is cold sinked. The bmc will control the fan, if the engine isn't to temp there is no reason to blast the fan on high.

Now, are you saying the block is to operating temp and you leave for say an hour to eat and remote start and come back to the truck and the hvac fan isn't running?

Your dealer needs educated.
 

Vehicle is a 2023 GMC AT4. Understanding block is cold in the morning but I don't understand the settings. You are saying that I have to have the settings in place prior to me turning off the truck if I want the heater fully engaged the next morning?
 

I'm sorry, no, not the dash settings. I don't really remember, but there is a max fan setting buried in the infotainment settings. I think under...settings... vehicle...comfort and convenience...remote start.
 

I'm setting on my ass having coffee by the fireplace, so I can't get to a truck.

But this is a screenshot of the mygmc app that also has the max speed setting for remote start...

I have the max fan setting on, not sure with AC but does not do anything for cold days and want the heat blaring. I have tried this about a month ago.
 

I would do a remote start at operating temp and see what happens. Then you'll have some info for your dealer to repair.

I know it will blast the defroster and feet, with a warm engine with a remote start so your dealer is confused or unaware.

Remote start the truck, it is 60 degrees and not even the seats or steering wheel heater comes on today.

Dealer says it is normal, I have to program the vehicle before I turn it off if I want the Heater to operate a certain way. I have tried this, sometimes it works but most times, it does not work.

Since having this truck, 2 speakers (same speaker location), 1 amplifier, 1 leaf spring, 1 DEF sensor, 2 updates, and 1 tail gate issue has had this vehicle in for service. I have not owned it a year yet.

im pretty sure it has to be colder then that for the seat and steering wheel heaters to activate. heres details from an older model but probably still similar programming. "During a remote start, the heated seats will turn on when ambient temperature is below 50 degs F (10 degs C). During a remote start, the cooled seats will turn on when ambient temperature is above 80 degs F (27 degs C). So if the outside temp is below 10c it should be working."
 

I didn't like any of the "auto" climate settings in the first few weeks of ownership. So I just set me temps I want, and in the winter, turn on all the vent options including defrost. On really cold days I set the temp up to 75 before I get out. That seems to do the trick for me. Truck is warm after a few minutes of remote start.

How did you do that? I can't seem to find a way to do it and the owners manual does not seem to cover that.
 

Are you using the AUTO setting in the truck climate control? If you don't use AUTO it has no way to switch to heat the way you want. IF you set a temp for auto and it's colder than that set temp the truck will provide heat once it's available from warmup.
