Performed HVAC recalibration first time I felt heat come through the ducts during the process after recal it did not work. second time it just had cold air coming through dash ducts. Rear heat works fine. |

Just to cover the bases make sure the engine coolant level is not low. Being a quart to a half a gallon low can cause insufficient heating in the front heater. If you have dual temperature controls check the vent temperatures on the driver’s and passenger’s side of the dash. Are they the same or different? These articles should help explain what to check.
