No Heat, Blows cold air
I have a 1998 Ford Ranger. My heater is only blowing cold air. I have changed out the Heater Modulator Valve, however when I try to adjust the heater knob, the valve does not do anything. The air compressor clutch engages on everything on the heating side. Any other ideas?

Look for vacuum lines off or broken that actuate the blend doors

Re: No Heat, Blows cold air
On the heater hoses I had to change the heater control. Maybe that is it
