Did you have the HVAC computer reset after the new parts were installed? This needs to be done so the HVAC computer can read the full swing of all the mode control motors and doors. Only a very good quality scan tool can perform that function and reset. So only a dealership or an independent shop that has the right equipment. HTH

    My heat and air conditioning are not blowing out any air. The air is cold and heater is hot. It's just not producing any air other than the vent when driving down the road.
