Does your ventilated/cooled seats actually work ?
Put it to ya this way. Glad I have it at all. Often in the warmer months I will drive around sometimes without it and start sweating on the seat. Starts getting nasty, turn it on and a few minutes later I am much more comfortable, so its better then not having it at all!

It's not super noticeable, but it works. There are three levels but I can't really tell the difference between them.
I think where it's more noticeable is over time on a long trip. I went east (from LA to the desert) for a full day and I noticed it actually worked in keeping my lower back dry.

I took my car to the shop to have it fixed. The tec said it was working fine.
I then brought my wife's car and turned both vehicles on at the same time, adjusted the temps to the same - turned the cabin air fan to off and the seat fan to 3 (highest setting) on both cars. Ran for 10 minutes and demonstrated that there is a VAST difference. Demonstrated to three people there, the General manager, the tech, and the receptionist ... all could feel a difference.
So ... they took the car for repair **I guess** ... they do not know how to fix it ... week four and no action has been taken. But there's clearly a difference.
Most would probably have "accepted" the first response: "It's working fine" as most do not have another car to compare it to.
However, having the same exact car (just one year older) I know better. Air conditioning seats are great - but when they are broke - techs do not know how to fix them.
