As many people have had this problem, My trucks heater is. Doing as many others only blowing cool air. It also I when accelerating the blower switches from the dash vents to the top vents used for the defrost then back to font vent when RPMs go back down. Done all the flushes changed. Thermostat and water pump. With so many complaining about the same thing it seems there is some kind of defect. Any ideas?
have the same problem?
