Of course this happens right as the temperature here in Wisconson is starting to turn cold. Anyways today I was getting no heat coming out of the vents. It was just blowing out cool air. It did work normal one time but didn't again after dinner. Anyone have any idea on what to do? Its starting to get cold here!!! Thanks.

 

Anitfreeze maybe low ,,, most times that is all it is,,,or air locked.

 

X2 check you coolant level. See if it gets a little warmer as the RPM goes up & listen for sloshing.

Next may be a thermostat. Look at your temp gauge and make sure your motor is hot enough
