Heater does not blow hot. It blows just does not blow hot.

This has alot to do with which vents you are talking about. There are 5 different distribution paths. Tell me which vents and I can tell you where to approach the problem. You have drivers side vents, floor, defrost and side defrost vents. And the same for the passenger side. You must be specific which one of 8 are not working in order for me to give you the right answer. Drive on......
