Super Hot Climate Control

[II Kings 9:20]

2021 Rogue SV Dual Zone.

It seems that no matter where I set the temp, the system blasts heat.

20F outside and whether the dial is set on 61 or 75, the heat blowing out is very hot.

It only cools off if I set it to Lo (below 61).

Of course, the AC is off and it matters not if I leave it on auto or manually adjust.

Thoughts? Anyone, Bueller, anyone,anyone?

I have not noticed this. Could be a blend door actuator not working. To be honest it has yet to get that cold. Yesterday it was 27f. I had it set at 69 and like clockwork.. the fan was on low till the engine warmed up. Then it cranked the fan to full and kept it there for a few minutes and then slowly backed it down as the cabin came up to temp. I didn't notice any major heat coming from anywhere. Just warm air.

Your vehicle should still be under full warranty. I'd say let the dealership figure it out.

The ones with dual control have three different sensors that need to work in order to modulate temperature. There's the ambient sensor which also provides the temperature on the dash, an in-cabin sensor, and an intake sensor which monitors the A/C evap temperature. Any of them will read dead-cold if they're bad or go open-circuit, which will cause exactly the behavior you're describing because the HVAC thinks the car is in Siberia.

Dozens of complaints going back to last spring on the other forum. I’m calling Nissan corp and dealer tomorrow. No fix but one member had the climate control unit replaced which worked.

We've got a 2021 Platinum.

Pretty similar situation here. About 40F outside. HVAC set to 61 and the heat is pumping no matter how long the drive is. One click lower to the Lo setting and now the AC clicks on. Our only solution is to set it to 61, then the lowest fan speed, then adjust the vent direction and your amount of clothes until you're comfortable.

It seemed unnatural to me. But I chalked it up to the cold weather outside (some days in the 20s). It's so cold outside that maybe the cabin temperature is indeed <61F, so the heat continues. Let me know what you find out. The operation is far from ideal, so if my HVAC controls or a temp sensor needs to be replaced, so be it. Dealer is over an hour from me, so I don't want to make an all-day trip out of this for them to tell me "everything looks fine."

Damn show a little fire and don’t settle for less. Why the hell should the heat kick in at 61.

It’s new, make Nissan fix that. If it was an old clunker, THAN live with it.

I’m so happy with my old school knobs where I can just dial in the temp, no mess, no fuss.

I guess just because I don't know what the cabin temp actually is. Maybe it's 30F outside and 58F inside, so the heat continues. That's how I've rationalized it, but half of it is because I don't pay a lot of attention to it.

Either sounds you have a great super hot heater made for Siberia, but the problem is that there is no gray area like mine where I could make it a little warm, or warmer, dial it higher here and there. Various increments of heated air. It’s not like it’s cold or super hot heat and nothing in between. Unless technology is going backwards, like if a tv only had zero contrast or 100% contrast.

Nissan got issues. Don’t rationalize your hard earn money, expect better craftsmanship not crap.

Then again it could be normal like a home heater where the hottest heat comes out until the home is at desired temperature and then shuts off. Anybody with additional insight feel free to chime in.

This is true. I've also got an old Ford Focus with manual controls and, exactly as you said, no issues dialing in the temp of whatever is blowing.

So even if Nissan says everything is working properly, at the very least, we need more degrees of adjustment then. As you said, it's all or nothing in the winter. 61 full heater, one click lower and it's full AC.

Same issue for me. 21 SL premium. It continues to blow hot long AFTER it reaches the set temperature. I am an “auto” guy. Every car I’ve owned for the last 30 years has the auto climate control feature. I get into friends cars and put it on auto. Maybe it’s the thermostat or where it’s placed in the car. It blows hot all the way down to a set temp of 61 degrees long after the temperature in the cabin had been warmed to well above 70+ degrees (at least it feels that way to me). Lower it to 60/Lonand it blows ice cold. There’s nothing in between. I will say that the problem seems to resolve itself after driving the car for an extended period of time. But not until the temp in the cabin is at least 10 degrees warmer than what you’ve set it to be.

I'm finding on longer trips it blows less hot on 61. I had to turn it up to 63 because it was getting too cool in the cabin.

When it's 20F outside it blasts heat for a long time.

When 44F outside, it blasts much shorter and 61 is less hot. I say less hot because 61 is not cool like other cars in the winter.

It's hot on short trips and much better on 30 min trips.

It is poorly designed (and I'm afraid "working normally") as I have owned over 65 cars and I've never had to run the temp on the minimum or feel the need to crack a window in the dead of winter. I'm wondering why none of the testers picked up on this during development.

I was going to have it checked last week but canceled since it does seem to be responding better to inputs. I have a case# with Nissan and will have it looked at after I get more experience.
