Truck Heater Problems

I have an 88 Ford Ranger. The heater will not get hot. I changed the heater core, thermostat, and radiator. Any thoughts?

This is a classic problem on Fords. Underneath the hood you will see a series of vacuum lines running along the edge. One or more of those lines are bad, causing the vents to not open and close when they should to release heat. Time to start checking those lines. (11/23/2010)
