My 2010 Terrain blows only cold air no matter what the temperature is set at. The engine temperature is in the normal range and the coolant is at the proper level.
Try purging air out of the cooling system. Youtube has some good video tutorials for this.
You are welcome. How about a thumbs up? The pay here sucks. ;)
wagner88324 did that help? I have a Terrain as well and am having the same issue.
