2016 little or no heat, long warm up

neontrucks · December 16, 2016

Is anybody else having problems with truck taking for ever to warm up. Also doesn't seem to blow good heat after warm up, and not much airflow from defrost. HVAC actuators have been recalibrated. Next step is dealer, just want to know if this is a common issue

Mine warms up fairly quickly and blows good heat so it's not normal if yours isn't.

Mines heats up with no issues. It heats up better than my 2014 did.

I have to do both remote starts (20 min) to get almost anything out the vents, and temp gauge still not to 160 degrees. No check engine, no t-stat code. Ambient temp has been about 5 to 10 Fahrenheit

OP, not sure what part of WI you are from, but the past few days in my part of WI have been below zero for highs. When it's that cold, it takes a long while for an idling motor to really get warm.

Green Bay, yes I agree will take a long time idiling. My 1998 seemed to blow warm in about 10 minutes or so at same ambient temp. Even driving in the city seems to take longer than I think it should.

Take it in for warranty service. The heating system is designed to work well. Our weather has been below freezing and I'm ready to drive with one remote start.

Check your cabin air filter. At 30 degrees mines usually toasty in 10 minutes. At 0 degrees this morning it didn't start blowing warm until 10 minutes of idle and 2 miles down the road.

I think it's the way it's setup having the auto feature. Also it goes by what it was set on when you last turned it off. Lastly it will take a lot less time to warm up the cab when you actually drive. Really modern gas engines don't need to warm up, maybe a minute even in the coldest conditions. You still have to take it easy at first since all you warmed up is the engine. You have to also think about the trans and axle. I know a diesel is a different story, but a gasser you're really just warming up for comfort in the cab. Even below 0 I would only remote start as I was about to walk out the house. I'm not wasting 20 minutes of gas idling just for the cab to be a tad warmer. When I had a truck without remote start I didn't even let it warm up much unless I'm defrosting the windshield then I'd let it warm up as I'm cleaning it.

I've had people even nitpick and complain that the AC doesn't get as cold, but only by a handful of degrees so not a big deal. I've read that people say it's because of the auto feature. It's just a different system.

Green Bay, WI here and no issues, even 2 days ago with like -2 temp, warms up quick and blows hot.

I'm with ya, defrost sucks, was like that on my 14, also it would be nice if they designed it so it didn't push air until it heated up, I think pushing all that cold air makes it worst, I'm thinking about going with a aftermarket for this reason

Been using manual setting, with auto it will almost never "satisfy" and runs at high fan speed. Yes I am aware modern engines don't need to warm up, I just enjoy having a warm truck when I jump in it. And it should be warmer after about 30 minutes of run time.

The way I figure, even an older truck will only take about 5 minutes or less to heat up real nice so I'd rather let it idle for a minute and then drive. Use less gas (even idle isn't using much, but over the time of Winter it adds up) and seems like it would put a little more wear and tear to idle for 20+ minutes just to have the cab warm. I've never had a problem driving in a cold can for a handful of minutes since I'll have a heavy jacket or hoodie on so really my hands are the only things that are cold for that short time. Well unless it's cold enough to want gloves then I'm fine all around. Just my preference I guess.

Have you checked the fluid level in the reservoir tank? Is it to the full cold mark. If the coolant system is low it could be causing it to take longer to warm also.
