Hi Tntfaguy,Excellent, thanks for the info, I'm having this same issue as well. Fan comes on full blast and shuts off after a couple seconds. Mostly does it with the a/c on, but it's not correct. Never stays on long enough to do anything. I would think it would come on and maintain a steady rpm for a longer period of time like my silverado and my wife's traverse. I'll have them do this when I take it in for the steering reflash.
Glad to see you are going to bring this to the dealership's attention! I definitely look forward to your updates with this, and if you need any additional assistance, feel free to let me know in a private message.
