What are operating temperatures we should be seeing for a normal working seat. I’m getting 80 for seat cushion on full blast and mid 80’s on seat back. I’m using a temperature gun.

Depends on the cab temperature.. I would say a 15 degree drop would be in the ballpark..

I have one of the first kits Tim made for my 2015 Platinum. I have cooling in seat cushions and back of seat that work great. Things that I have noticed that can make a difference. First thing if you do not inflate the bladders for comfort there does seem to be more air movement over inflating them especially on the back. Second thing is I noticed the seats not cooling as well one day and looked around and found the problem. My exhaust hose was not as long as I would have liked and the carpet flap that folds under the bottom of the seat was right up against the exhaust hose blocking air flow. Folded the carpet out of the way and the seats went back to cooling I was use to with Tim’s kit. Temp was 93 yesterday and had cooling top and bottom that was actually cold enough for me to turn it down to second setting. Can’t thank Tim enough for making this kit to fix our seats.
