If the blower has stopped then check the fuse box. If it just blows cold air after the engine is warmed up then your heater core needs replaced.

If your heater continues to blow cold air after you have driven for ten minutes then most likely your heater core needs replaced.

If it's blowing cold air check the water valve behind the engine. It's made to stop hot coolant from going to the heater core if a/c is on. they like to fail. feel the hoses on either side of it and if one's hot and one's cold then it may be malfunctioning. If the hoses are different temp then unplug it and check voltage at the plug it should go 12 volts one way when turned to cold and 12 volts the other way when turned to hot. If it needs replacing it's part of the hose that goes from the heater core to rear of engine behind intake. Don't just assume it's the heater core that is a much more expensive repair and not usually necessary.

My heater blows out cold air will not blow hot air out. Do you think it's the heater control valve or could it be something else. Cold air works fine just no hot air.

My valve is making a clicking noise for about thirty seconds when key is turned on and then off doesn't matter which. No warm air, hear the temp controls change, no water coming from heater core. Sounds like the valve. Yes

All u have to do is take the cover off the heater control valve by removing the 3 screws. You will then see a set of gears they will just pull out. The one at the top right is the biggest round gear u can pull that off then there will be a piece behind it that looks like a cross turn it to the left and that will open up the lines so the water or coolant can flow. Then the heat will work. You may also be able to put the gears back in and it will work fine. Some times the flap gets build up around it and just needs to be broke free

I have change the climate control panel, I have flushed the heater core, I have checked the electronic control valve. One side was hot and the other was cold, I turned the controller 180 degrees and the other side heated up. What else could be causing the heater not to work? Cold air blowing only.... Also got the clicking sounds fixed on recall last year.. 2010 Titan CrewCab -
