B1081 Ford Code - Temperature Damper Motor Circuit
Quick Answer
o rotate the temperature blend door actuator, the Heating, Ventilation, and Air Conditioning (HVAC) module supplies voltage and ground to the temperature blend door actuator through the door actuator motor circuits. Common causes include Faulty Temperature Damper Motor, Temperature Damper Motor harness is open or shorted, Temperature Damper Motor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code B1081 Ford Description
The temperature blend door actuator feedback resistors are supplied a ground from the HVAC module by the temperature blend door actuator return circuits and a 5-volt reference voltage on the temperature blend door actuator reference circuits. The HVAC module reads the voltage on the temperature blend door actuator feedback circuits to determine the temperature blend door actuator position by the position of the actuator feedback resistor wiper arm.
During an actuator calibration cycle, the HVAC module drives the temperature blend door until the door reaches both internal stops in the HVAC case. If the temperature blend door is temporarily obstructed or binding during a calibration cycle, the HVAC module may interpret this as the actual end of travel for the door. When this condition occurs and the HVAC module commands the actuator to its end of travel, the airflow may not be the expected temperature.

I can hear something behind my dash panel making a clicking noise when the temp control is moved from hot to cold. It continues to click, but if I turn temp control back toward hot just a bit, the clicking goes away. I'm pretty sure my blend air door motor is failing!!
