Hi,

'17 GT AWD owner here, today i have discovered that the rear AC vents are way way way cooler than the fronts,

Any one noticing the same thing?!

And does any one knows how to change the AC filter?! I googled it and no FSM was found.

Thx

I will put a infrared temp sensor on both and see, but I expect they are similar.

So I ran them both full blast A/C with a infrared temp sensor

Lower temp recorded for each:
Front vents: 42 degrees (F)
Rear vents: 39 degrees (F)

So rear vents a few degrees cooler than front.

Note: a refrigerator optimal temp is 38 degrees. The CX-9 blows 39 degree in the rear. That is colder than any vehicle I've every had. I think this should put to rest "the A/C sux" malarky.

Hmmm,

Mine doesn't fell like 3# difference, more like 7 to 8,

I will take it to the dealership and let them figure it out.
