I've notice that my 2010 Escalade fan comes on way too early! The car can be cold and the fan will come on full blast. It's very loud and makes me wonder why it comes on so early. My previous 2010 didn't do this until the temp gauge got higher. My current one will sometimes come on when the temp gauge isn't close to getting to normal operating temp. Dealer wasn't much help when I asked them about it and warranty is gone so I'm definitely not taking it in there. Any ideas?
