Default 2007 lt hvac controls
Cant get any airflow thru the vents, only from defroster or floor, had one guy tell me the digital panel is bad and another tell me actuator-is there anyway to check these? Tried the fuse and letting it recalibrate but that didnt work. Thanks for any info

Welcome to the forum...
If the re-calibration did not fix it, its likely a bad blend door actuator...
