FORD F-150 PANEL PROBLEM

1999 Ford F-150 • 185,000 miles

When heater is on and switch is turned to floor, heat only comes out defroster, the when turned to panel heat comes out of panel then switches to defroster then back to panel and keeps repeating every few minutes. Not really worried about the panel, just want the heat to be able to come out on the floor.

I would check the mode valve most of them default to defrost when they fail.
