Heater has stopped working?

Try pulling hvac fuse for 60 seconds first sometimes the actuators reset. Otherwise see if the blend door actuator is getting power or not you have to get to from passenger side an dpull down hush panel also check out this guide.

Check out the diagrams (Below). Please let us know what you find. We are interested to see what it is.

Hello,

It sounds like you have air trapped in the heater core not allowing coolant to enter or you have a temperature blend door actuator not working here are two guide to help you get started finding and fixing the problem.

Many of the 4 cylinder engines need to be burped after refilling the cooling system. I would try raising the car in the rear with the engine running and heater on full blast. See if the coolant level drops.

Neither. The bubbling points to a leaking cylinder head gasket. Your mechanic can perform a chemical test at the radiator cap to verify this. The test involves drawing air from the radiator, while the engine is running, through a glass cylinder with two chambers partially-filled with a special dark blue liquid. If combustion gases are present, the liquid will turn bright yellow.

Here's a link to an article that explains this in more detail:

You probably need to check for hvac codes, barring that, try the above procedure.

Do the radiator hoses and heater hoses get hot?

I'd have to check the circulation in the radiator and heater core.

One of three things:
1. Low coolant level. While you are checking the level, ask yourself. When was the last time you have the coolant system flushed? You may also have "air pockets" in the cooling system. Have you ever have to add fluid into the cooling system? If you or a service station used water, instead of coolant, that will reduce the quality and efficiency of the entire system.

2. Thermostat stuck open. Locate your radiator hoses. Grasp the hoses (one at a time) and squeeze them. Are they both warm to touch? If they are, the thermostat is possibly good. If one of them is warmer than the other, replace the thermostat.

3. Restricted heater core. This goes back to #1. If the cooling system has not been flushed for the past say 30K miles, you may have a lot of gunk in the system that prevents coolant flow, especially if you have been adding water or low quality coolant.

Follow the diagnostic from 1, 2, and then 3.

Please advise.

First of all, go to an Autozone or CSK/O'Reilly and have them scan your PCM and get back to us the the code(s), number and description.

If steam is coming out of the engine, usually you have a coolant leak in the engine. You need to visually check the entire engine and find this leak. You may want to replace the thermostat in this vehicle.

I need you to check something. Start the engine, let it heat up with the heater on high. Feel both heater core hoses. Both should be hot. If they are, check the blender door operation. If one is hot and the other not, chances are the heater core is plugged.

Let me know what you find.
