I doubt you have any mechanical issue with the engine or cooling system. You probably have a blend door that is not completely closing, so the hot air from the heater is blended with cold outside air.


That sounds most plausible.

From everyone's feedback, it seems like something's not right. Will take it to get checked out.

I appreciate the help everyone, thank you.

Yep, that's not right. My 2014 starts cranking out strong heat within a few minutes. fwiw, I once got a CEL when my thermostat was opening too soon so I agree that's likely not the problem.

As stated above, before taking it anywhere to be checked, check the antifreeze level yourself.

I had an old Chevy snow plow truck that had a leaking radiator in it that I attribute to never having flushed the cooling system or changed the antifreeze in, that wouldn't put out sufficient heat when the radiator had lost enough coolant. Fill up the radiator, and it had great heat.

So check your coolant tank. It will have low and high marks on it. Even if it's not below the low or fill mark, fill it up to the full mark and see if it makes a difference.

Except on a new(er) truck, you'd get a low coolant message long before it got low enough to not fill the heater core. Likely not the issue here.

Agreed... Sounds like a blend flap issue...

Now that winter's properly arrived I'm noticing that the heat in my 2017 2500 isn't that powerful. It takes a good 20 minutes to heat up the cabin into the 70s. It can't compete with any windows being open even partially.

Anyone else noticed the same? I have the super basic work truck heat, single zone with three speed fan.


Did it used to keep the cab warm with the windows partially open? Does it work okay with them closed?

I can start my truck, turn on the exhaust brake, and my truck is toasty in 5 minutes. But that is diesel; I would think your truck should heat right up itself in about 5 minutes. But with that being said, when in the heat position- pointing right at you- I don't get that much of an air flow. In other words, my heater doesn't blow very hard. I'm wondering if it's because the vents in the backseat of the cab are on, and it's such a large cab. Do you have that problem? Somethin' ain't right if you're not heating up.

Our 2016 Hemi 6.4 works fine. Last February when coming across the U.S. we encountered cold temps while driving and the gauges showed the thermostat would cycle between 185 and 206 quickly. Once the temps warmed up, the swings in engine temps stopped.
Take it in---there are several recalls popping up that might be on your truck too.
