LINCOLN NAVIGATOR HEATER PROBLEM

2003 Lincoln Navigator • 135,000 miles

My 2003 Lincoln Navigators heater stopped working. It's my understanding that there is a front and back heater core so I'm ruling out a heater core issue since there is not heat at either position/controls. I've checked the coolant level which is fine. The fan is working/blowing and produces only cool air. Any ideas of likely suspects? Thanks

Blend door motor may be bad. Is there any noise coming from behind the dash?
