AC / heat in rear seat

[Kevin Mokracek]

This is exactly the right approach. I also posted this at some point last summer. I always control my heating and air conditioning in combination with the Auto button. Then the temperature can be adjusted from very cold to hot. It is important that Auto, the air conditioning button and the rotary control are always seen as a single function. That's why I generally have no problems with the system.

When I hit the Auto function button it turns the fan up all the way to high which is too much and too loud. If I try turning the fan speed down while in Auto function it turns everything off. Also while in Auto function using the temperature control turns the whole system off. I’m sure that’s not what is supposed to happen.

Do you have the latest 1946 software?

I have no idea if I do. I took it in to get the trailer hitch installed about a month ago and they did a software update for that but it dint change HVAC problems.

First check the vehicle menu to make sure you have the 1946 version. Switch off the climate control button. Then use the rotary knob to select the temperature you want to feel (e.g. 23 degrees C). Then press the auto button. Depending on the previous interior temperature, the air conditioning may switch on automatically and the fans may blow strongly. However, this should subside over time. If the temperature is almost the same, the fans should turn normally.

MY24 vehicles use different firmware revisions, so 1946 doesn't apply to the newer vehicles

I didn't know that. Thanks for the clarification.

Had our Grenadier 4 months now, air con has now failed 42 times now with exact same problem.
It randomly decides to open heat flap resulting in piping hot air to back vents and a mix of aircon and hot air to the front. No adjustments resolve it. The only resolution in to stop the car , switch off, lock walk away for 20 minutes and come back. Mostly it works, but sometimes it stays the same.
Brisbane dealer says waiting on new aircon hose., so far 2 months---
Seems more like a software issue applying heat flap.
Has anyone had the same issue? If so, has it been rectified.
With ambient temps in Queensland 27 to 35 deg the vehicle is sometimes undrivable.

yes, exactly as you describe it. Mine was blowing hot burning in the back vents and kind of cooler on the front..... stop the car, lock it went for a light coffee and then it was fixed by itself..wtf happen.. no idea but now in mid cold it works perfectly. same happened with the tire sensors and temp gauge.... is like a the grenadier is moody

I have identical problem with my air con.. cooler air with the two front side vent. front center vent is slightly warmer. rear vent blow hot air... time to complain to the dealer...

Ineos, FTLOG, please make the HVAC controls a simple, mechanically operated system in the next refresh:

I recognize by Discovery dials in the first photo ! 28 yrs and still incredibly accurate!! I dislike "electronic" systems as I don't get it when the heat is on and cold air blows! I think the "G" system has a mind reading component - on a long drive today with highs 90F and was thinking doesn't feel like very cool air blowing and suddenly I had cold air. This vehicle is possessed!! Love her

Anyone know if there is a way to disable the hot water flow the the heater core? I am talking about "low tech" like unplug a valve electrical connector....

I understand people wanting automated electronic gizmos run by a computer chip attached to every single thing in a modern vehicle, and Ineos wanting to meet that desire, especially at the current asking price. But what I was hoping Ineos would have done is to have a “stupidly simple” base model without all of that and instead offer the techno wizardry in an upgraded option package. Or better yet, offer every single item as an option. These “take it all or leave it all” packages I know are much more cost effective for the volume manufacturers, but I’d be willing to pay MORE without all of the “luxury” extras that I don’t want or need in THIS vehicle.

Have also been having aircon issues ie, hot air from all vents, cold at front hot at rear etc, even after the major software update. The aircon was recently re-gassed which has improved performance, but there is still regularly hot air from the rear vents, even one occasion with hot air from the left rear vent and cold air from the right rear vent (didn't know it could do this) Like may I find it works more reliably on auto. If there is an issue, turning the temperature all the way down to low and letting it blast for a minute before turning it back up seems to help reset the rear vents, sometimes. It is nice the times it just works though .

My systems went haywire again this morning, with the aircon very confused about what the temperature should be (regardless of any attempts to encourage it to work) and the engine cooling systems blowing a gale (the radiator fans were screaming). This happened just after starting on a cool 13 degree (celsius) morning driving only a few minutes in light traffic. When this happens the start-stop function also stops working (probably due to the radiator fans drawing so much current). Even if I pull over, stop and turn the engine off, the radiator fans keep screaming.

It’s like there is a glitch in the software, or information from one or more sensors confuses it, creating a loop that it can’t break out of, so it just goes into some sort of engine protection default.

Usually, after about 20-30 minutes of uncomfortable driving it seems to reset, the radiator fans finally calm down, the start-stop resumes function, but the aircon doesn’t always come back to ‘normal’.

With the aircon, the rear vents must have their own sensor, as they seem to be set to several degrees higher than the front vents, if I crank the temperature right down, the rear vents cool down, but are often still warmer than the front vents. Could it be that there is a setting in the software that is different between front and rear, or inconsistent information from front and rear sensors that is causing the cooling system to get a bit confused, or different types of sensors front and rear resulting in different readings, or a bad batch of sensors .... ???

Hopefully, with more information, the boffins at Ineos can figure out what is going on and finally fix the problem/s.

I have had the same issue like 10 times, such a pain especially as it is getting warmer / hot here... any solution from the dealer?

It happened to at least 4 times already, I called Ineos Customer Service (Telephone number: +1-833-494-4748) and to my surprise I got a called back asking me a very detailed info on how it happened, so they can start a report to INEOS HQ. I told them to go online and read the Forum, which has plenty of info from users all over the world..(australia, Qatar, US) with the same issue
Also they emphasize to bring it to the dealer so they can fix it...... not sure they know how to do it yet...

Part of the "bring to a dealer to fix it" is that the dealer can run additional diagnostics on the blend doors and the HVAC system in general to see what is going on to cause it, and at the very least pass that information along

Less than 500 miles on my trialmaster. Driving today and it got warm so flipped the aC on… not very cold air in front and vents in back seat were blowing hot (really hot) air. Is there a chance that the AC wasn’t charged before I picked it up? My dealership is 2 hours away so I can’t just drop it off…. Any advice would be much appreciated!

i'm late to this. But i had the exact problem. My AC was OVERCHARGED by 20%. so it was freezing the valves, which is why i was getting full heater air in the back seat. The dealer corrected the charge amount for me and i have had a problem since.

 

[trobex]

Same here as OP. Rear vents blow hit air on and setting over 24c. As in very hot air circa 30c is what it feels like. Put the AC on 24c and the yep the temp is 24c... just odd. On list for dealer.

 

[Mudnut]

Still waiting on my Quartermaster to arrive in Q4. Wondering if the rear vents can be closed if they are blowing hot air when i want AC to cool? Might at least make it more comfortable whilst getting to a location to stop and turn off the vehicle to reset.
