Ventilated seat not cooling on bottom?

[jacksonian]

Yep, I knew I could look in the iDrive climate settings and adjust more/less to the back or bottom cushion. This seemed weird though, I always keep that in the middle and it really felt like the bottom cushion was actually heating up, not even staying neutral. I turned it on/off a few times and it seemed like maybe this last time it started to cool a little. So I'm not sure if something's not working correctly or what. (and the rear seat climate control was off, but that's a good tip).

I'll see how it does over the next few days and take it in for service if it keeps up. But my fear is that a tech will turn it on, hear the fans blowing and say, "It's working fine."
