Let's get some perspective: Is your Grenadier AC working as it should?

[G-Man]

Who else's AC is batsh1t crazy and randomly blows hot air one day and cold the next on the exact same setting? I don't think the AC system got the attention it deserved during the 1.2 million miles of road testing, that's for sure. I love my new truck but it's the one thing that drives me nuts on pretty much a daily basis as I fiddle away at the controls and I'm surprised Ineos haven't found a fix for it yet. I gather it's down to sticky solenoid valves or such like and is probably an expensive warranty concern for them.

It would be useful to set up a poll on this forum and get an idea of what percentage and numbers of owners here have flaky AC. This forum must represent a decent amount of the Grenadier owner population, perhaps it would help sharpen Ineos' perspective on the issue if it popped up on every Google search relating to Grenadier AC issues. I don't have the ability to raise a forum poll but maybe @Stu_Barnes would consider it a worthy exercise

It’s super frustrating because I think the HVAC is erroring-out in flame mode, but is just the whacky sensor(s). I will only have access to cooling at the extreme end of the dial, anything less produces heat. Driving for a while usually gives a few more AC clicks, but shouldn’t this be based on driver demand not vehicle limitations?

Particularly on the East Coast, there are time you don’t open your windows due to pollen.

Mine works fine (5/24 build date). I have never had any of the issues some have complained about. I put it in auto... set the temp and don't touch it.

For AC, I mainly just set mine to max low and use the fan speed to modulate temperature. It seems to come with the extra benefits of stopping the start/stop from triggering. This may not work in cooler climates though.

Same here. I never have start/stop activate, unless it is winter and my a/c is off.

Finally got the A/C bug where the system wouldn't turn off and blowing flaming hot air. Was on a road trip and the thought of a few days of this was not pleasant, but this forum is a valuable resource. Turn if off, lock the doors, let it sit for 5-10 minutes (I guess 5 minutes, 30 seconds is the key) and all back to normal. I normally run in auto and haven't had a problem since I purchased in February.
