This thread is about 7 months old - and I'm not sure if my issue applies to it or not - I think it does:
My 2016 Limited has the cooled seats. Living in Arizona, it's an option I LOVE having (just like having the heated seats and heated steering wheel in the winter when it's 30 degrees (and my steering wheel gets hot all the way around - noticed some people saying that only parts of it heat. I use it a lot, it helps with my getting-old-man-hands arthritis!). I've had the car coming up on 2 years in Oct. The cooled seats have always worked GREAT in the summer. Turn them on Level 3 and eventually need to go down a notch, sometimes 2. And the lower part of my seat-back does blow cold or hot.
I'll now have to put that in past tense - the seats USED to blow cold/hot from the cushion and seat back. I noticed about a month ago that my seat wasn't getting cold anymore. I put my hand under my thigh and nope - no air coming out. It was the same on both front seats. About a week after noticing this, they worked again for a trip (both seats), and now they've gone out again and have not worked in several weeks.
If I turn the stereo off and the A/C blower down, when I push the Cooled Seat button, I can hear the fan turn on in my seat - but no air coming out at all. I thought perhaps there was a filter or something that clogged, which is why I came here to look.
I tried clicking on the TSB cwescapexlt4x4 linked in his post and it doesn't allow me access. I need to take the car in soon for maintenance and I'd like to know the whole scoop on this "cooled seat" issue before I go.
Any new info on this? Suggestions? Advice?
