The rear blower fan cuts on just fine but there is no heat. The front heater turns on with blower and heat but doesn't change from vent to floor or anything than what is presently set on. HELP, where do I start first? :cry:

This is two different problems, please start a new question for the front heater problem, we will handle the rear heater problem on this thread. There is a temperature blend door actuator that needs to be change out which should fix the problem. Let us know if you need anything else.
