Some 2015-2020 F-150 and 2017-2022 F-Super Duty vehicles may exhibit a lack of heat or cooling from the cabin vents when the climate control settings are adjusted between hot and cold. This may be due to a stuck/binding temperature door within the climate control housing or binding/inoperative temperature door actuator. Diagnostic trouble code (DTC) B1081:07 may be present in the front controls interface module (FCIM) or heating ventilation and air conditioning (HVAC) module. To correct the condition, follow the Service Procedure to remove the climate control housing and replace the temperature door cam(s), lubricate the temperature blend door bearing surface, and apply flock tape to actuator to seal out debris. |
