My heater stays on when I have my a/c to cold

The Explorer and F150 are built on a different chassis, so there is no direct correlation of problems. However, air conditioning and climate control is typically similar as systems across vehicle lines, so you could have a similar problem. What problem are you speaking of with the Explorer? Can you explain in a little more detail the problem that you are having specifically?

Check your blend door, if this is stuck in the open position you will have heat coming out of your heater core all of the time.
