1998 Ford Ranger 4 cyl Two Wheel Drive Manual 106000 miles
my 98 ranger has no heat at all. I've checked the gate, fluid level, and the truck is running at a normal temp. The heater control valve vacuum line has no vacuum on it no matter what the temp control is set at. I've tried manually opening the heater control valve and still no heat. Where does the line connect to once it runs inside the firewall? What would cause the line to lose its suction? How can I test the temp selector knob?
