B11E7 Mercury Code - Air Distribution Damper Position Sensor Circuit
Quick Answer
To rotate the defrost/panel/floor mode door actuator, the Heating, Ventilation, and Air Conditioning (HVAC) Module supplies voltage and ground to the defrost/panel/floor mode door actuator motor through the actuator motor circuits. Common causes include Faulty Air Distribution Damper Position Sensor, Air Distribution Damper Position Sensor harness is open or shorted, Air Distribution Damper Position Sensor circuit poor electrical connection. Severity is Low - monitor the vehicle and repair when practical. The vehicle can usually be driven if no severe symptoms are present, but symptoms should be checked before extended driving.

Code B11E7 Mercury Description
The defrost/panel/floor mode door actuator feedback resistor is supplied a 5-volt reference voltage and ground from the HVAC module. The HVAC module measures the resistance on the defrost/panel/floor mode door actuator feedback circuit to determine the defrost/panel/floor mode door actuator position by the position of the actuator feedback resistor wiper arm.
During an actuator calibration cycle, the HVAC module drives the defrost/panel/floor mode door until the door reaches both internal stops in the HVAC case. If the defrost/panel/floor mode 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 from the expected outlets.
