Now that we're experiencing cooler termperatures, I'm beginnng to think the electronic climate control in my truck isn't operating properly. It's cycling really cold air to pretty warm (heated) air on a consistent basis. I had EATC in my Expedition and the temperatures didn't vary to these extremes. How are your systems operating? I hate bringing my truck in for warranty work.

 

I've noticed the climate control in my truck seems less than accurate, sort of like you're describing. I've sort of just gotten used to it.
