FORD F-250 HEATER PROBLEM

2005 Ford F-250 • 10,040 miles

What makes the heat only blow cold air?
the air only works on low and med not on high but when you change over to heat it only blows cold air not cool but cold as if you didn't change the temp or anything it will change to defrost and everything but still only cold air.

Check fluid level first, then check to see if actuator in heate is stuck or not working. There should be 1 on top pic enclosed

The shut off valve stops the flow of coolant to the heater, both hoses hould be hot or about the same temp. Check to see why it's not working.
