This HVAC system uses servos to adjust the settings, sometimes they get messed up and out of sync, you can try to get then to resend by Removing the fuses from the HVAC system and wait at least 10 minutes, then turn on the key, do not start, and reinsert the fuses, this should reset the system, if it didn't work then you will need to,take it in to a shop you trust and have the codes for the HVAC diagnosed.

System did not reset. Problem continues to be a nuisance.
