Default 2010 Heat Issue

I have 2010 Chevy Malibu LT. The issue I am having is the heat goes in and out. Seem that sometimes I start the it will get hot others it stays cold. Also seems to happen more frequent on colder days. I changed the thermostat didnt solve the problem.

Can someone help me live in the midwest its cold.

Could be a problem with the temperature door in the HVAC box. I just don't have enough info.

Auto or manual climate control?

What is the coolant temperature gauge reading?

Wow thanks guys for your replys. Well it is manual control and the coolant temp is at its normal operating temp.

For the temp door sounds like the dash would have to come out.

Burp the system requires what?

No, it does not. The actuators are pretty easy to replace.

When you rotate the temp knob from one extreme to the other can you hear the actuator motor operating? Get your ear up close to the HVAC box. You can both hear & feel the actuator motors when they run.

I just figured if you were the one needing the burp maybe you need better beer.
