Rear HVAC...

[Fellsteruk]

so I need some help because I must be missing something...

So I’ve had my gratin and AC set to full and on every combo of options faceonly, foot only, face and foot, windscreen, you name it I’ve tried it with and without someone in the back and basically nothing comes out the rear vents?

I know it only comes on when ppl in the back but how many people do I need back there?

You’ll find nothing comes out of the foot vents either.... the air con controls are not the MS’s strong point.

Must be something wrong. Our MX rear vents work fine with just one small child sat in the back to trigger them. I presume you have a 6 or 7-seater with the extra rear unit? Reported issues with rear venting are not uncommon on this forum and often traced to missing bits of ducting etc! Probably need to get it checked out by your local SC.

No rear HVAC for you!
What exactly do you mean by rear vent? The C pillar would not have any vents in a five seater. The backside of the center console should have air when the front is on dash setting (not all-defrost or all-footwell). I believe the B pillar vents are for the rear HVAC only

The b pillar has vents for the passengers in the 2nd row. Nothing comes out of them, are you suggesting they are for show?

Tesla said it should work but dependent on passengers being in 2nd row but I’ve sat in there myself and had nothing coming out.

 

[Gwgan]

Not for show, but for the sake of making one B pillar for all cars there is nothing connected to those vents without the rear HVAC.

Put it on full and got in the back with fWD closed and there is a flow coming out but it’s like someone with a slight blow nothing like the air coming out the centre console in 1st row

What exactly means. fWD?.. I'm in the same situation!.. My tesla MX even if someone it's on the back nothing it's coming out thru the vents!. No AC, no heat!

Falcon wing doors. So basically I’m in the back with the doors closed blowersbon full so I could test for myself.

Nothing but a pitiful bit of cold air so small I doubt you could measure it but define thy something as AC was on full belt but then the two vents in the centre were as I’d expect not as fast as the front but decent flow of air from them.

I think this could be an inherent weakness of the 5-seater X. When I was researching the X before buying one I came across a number of threads complaining about poor climate control in the rear of the 5-seater X. The 6 and 7 seater versions both have additional dedicated rear climate control and it was this feature that swung us into paying for the 7-seater. We have never yet used the rear row seats (probably never will) but the rear climate control seems good for our kids in the second row and it has separate rear temperature and fan controls (which I presume you don't have in your 5 seater?).

But still worth getting your service centre to check that your climate control is working properly as there have been no shortage of missing bits of ducting reported in other threads!
