No Warm Air From My Heater This Morning, just cold air. Also, no messages or warnings.

Has anyone experienced this issue and had to have it fixed?

Thanks.

Did you verify the Heat option was selected in your HVAC section of the Sync screen? I assume you don't have physical HVAC buttons.

You checked your coolant level?

Yes thanks. I tried everything. I haven't tried disconnecting the 12v battery to reset everything.

What year model is it? It makes a difference.

The diverter valve or the PTC heater might have failed.
Hopefully your coolant level is within spec and you don't have an empty bottle.
