I need help QUICK if possible. Just ordered the (heatertreater) Auto replacement part, blend door fix, Heat, AC replacement parts spacer for the blend door but I won't get the kit until sometime next week. I NEED to fix the broken spacer TODAY because I'm leaving on a road trip. DODGE has the factory plastic spacer I'm going to use till I can replace it with the Heater Treater peice, BUT I know there is a 'calibration sequence' heater treater sends for the actuator motor, does ANYONE know what it is and can share with me PLEASE?
