'16 XL SLT seat cooling temperature

[Arthur]

Newbie question, not sure if this was covered before, but the question I have is regarding front seat cooling on 16 Yukon SLT. It seems to me that after the visit for service the tech has adjusted something under the leather and now the seat doesn't seem to be cooling or heating as it did before. Is it possible that something between the cushion and the leather has been misaligned and restricting the air flow?
Thanks

I could use some advise on this as well as my drivers side seat used to cool in the lower back area and the seat itself, now I only get/feel the seat and not so much the back of the seat?
