Heater not working!

How did the fuses look?

Did you check all I listed in your other post with a test light?

I say this so much that I make myself sick, but this sounds like a ground that was left off or is loose or has a bad connection. Is the heat control knob striped?

Still check the grounds. The A/C works? The heat on and off controls the valve that opens the coolant. Obviously there is a problem with the valve regulation and this could be ground or a loose connection.

Hi and thanks for using 2carpros.com.

There are only a few things that can cause this, low coolant, plugged heater core, or a bad blend air door actuator. Take a look through this link:

Now, if the coolant level is full, start the engine and turn the heater on high. Wait until the engine reaches operating temperature and turn the engine off. Next, there are two heater core hoses that you will see attached at the firewall under the hood. Feel both. They both should be hot. If they are, suspect a problem with the blend air door. If only one is hot, suspect that heater core is plugged or the heater control valve isn't working. I attached a picture of the control valve to help identify it.

The valve is located under the hood at the fire wall and will be attached to one of the heater hoses. Have a helper change the temperature controller in the vehicle while you watch to see if the control valve is moving. If it isn't, then either there is a cable problem or the valve is corroded or rusted shut.

Do these things and let me know the results so I can direct you to a fix.

Take care,
Joe

Hi jemintun,

Seems the cable has been dislodged or improperly adjusted. Check if the cable housinng is seated properly on the clip.

Check if the heater hoses from engine to heater core is clogged or might have been disconnected.
