Or a leak of r134 refrigerant in the hvac system.

The redesign COULD be due to the phase out of r134a refrigerant? I think 2026 is the year that has to use the new standard?

If someone this is happening to can check to see if their AC compressor is not spinning, that would be a sign that this is the culprit. Every vehicle I'm aware of is designed to stop the compressor spinning when it's out of refrigerant as refrigerant is what lubricates the compressor.

If it is, then run to the auto parts store, grab a cheapo can of refrigerant, and charge it up to see if it works again. If it does (assuming the leak is slow and not a giant hole somewhere), then you know what's up.

This all, of course, applies to someone who lives a decent distance from a dealer. If you are right near one, it's their problem.

The proper way to do this would be to run down to the local pep boys or similar and have them evacuate your hvac. They can tell how much refrigerant they removed. Then they would hold the system under vacuum to test for leaks. If it doesn’t hold vacuum, you have a leak. Then refill with appropriate amount of refrigerant and you’re good to go. If there is a leak they can add uv dye to find it.

This way you know exactly how much you had vs how much you should have.

Not sure why, but I just bought the HVAC system from a wrecked Grenadier. It's from a 2023 RHD diesel model. Obviously missing the blower motor, but all the valves and flaps are present. It's not very complicated.
Will make a video about it very soon. I want to study its habits first...

Start a thread and post pics when you dig into it. I’m curious of the flap actuators could be replaced with cable actuators.

Yes, for a price that was a no-brainer in my opinion.

Yes, that's the plan. Anyone wanting specifics can ask. I want this to help everyone.

That’s two of us on here who have had bits off that vehicle.

Can anyone provide detail on which valve is deemed faulty and what the original purpose of that valve is? Same with the flap?

Year and build date?

Build date Sept 2023. Mine was on the first boat to USA

Had something funky happen to me today while driving which I have not experienced before; outside temp was showing as 19c and a bit more humid than usual for these parts, but the AC was getting a bit too cool so I shut off the compressor but still had the fans running. A few minutes later a very fine but dense fog or mist started pumping through all four front facing vents which lasted about three seconds, looked very much like smoke so I thought something had caught fire in the engine bay! Very weird.

Mine turned out to be three ground locations for the HVAC system (two on the passenger side one on the drivers) that too much paint or coating preventing a good ground. I will know if it’s good once it gets down to -25, -30 again.

Thank you. build date can be found on vin sticker in the doorjam

We need to discover where these ground points are. Any idea?

I can ask, there is two on passenger side and one on drivers. Labelled GND-P01-R, GND-P00-R, GND-P01-M. It appears they were working just up under the dash and passenger glovebox.
The service advisor said there was some acknowledgement from Ineos, not sure if that's a TSB or just an advisory.
I don't have access to the online service manual or I would it up, if someone does can you post pictures?
