Summary

Some 2015-2019 F-150, 2017-2019 F-Super Duty vehicles may exhibit a lack of heat or cooling from the cabin vents when the climate 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). To correct the condition, follow the Service Procedure steps to remove the climate control housing and replace the temperature door actuator(s) and/or lubricate the temperature blend door bearing surface.

Service Procedure
1. Using the datalogger on the IDS scan tool, pull up PIDs LEFT_BLEND# and RIGHT_BLEND# to
monitor temperature door operation. The LEFT_BLEND# PID is for the driver's side and the
RIGHT_BLEND# is for the passenger's side. Using the temperature knobs in the vehicle, change the
temperature from LOW to HIGH and back to LOW and monitor the percentage for both PIDs. Do the
PID percentages change from 0-1% up to 99-100%?
NOTE: For vehicles with manual climate control, both PIDs may not be present.
(1). Yes - this article does not apply, refer to Workshop Manual (WSM), Section 412-00.
(2). No - proceed to Step 2.
2. Proceed to the appropriate procedure based on the condition.
(1). If either PID shows little to no percentage change, this is due a driver side temperature door
actuator concern; complete Procedure A.
(2). If either PID shows a percentage change through most of the range, but not all, this is due to a
binding cam follower or temperature blend door; complete Procedure B.

Procedure A: Remove The Driver Side Temperature Blend Door Actuator
1. Gently wipe the driver side temperature blend door actuator, cam, and cam follower attached to the
climate control housing blend door to remove any debris and existing lubricant.
NOTE: Do not remove the cam follower from the climate control housing blend door. It is critical to
be gentle when cleaning the cam follower as damaging the temperature blend door shaft will
require replacement of the climate control housing. (Figure 1)

2. Replace the driver side temperature door actuator and cam. Refer to Workshop Manual (WSM),
Section 412-00. Reapply fresh grease to the cam and cam follower pin using Motorcraft® HVAC Duct
Component Grease.
3. Reassemble per WSM. Test the temperature blend door operation. Does the system operate properly?
(1). Yes - repair is complete.
(2). No - proceed to Procedure B.

Procedure B: Lubricate The Temperature Blend Door Bearing Surfaces
1. Remove the climate control housing. Refer to Workshop Manual (WSM), Section 412-00.
2. Follow the evaporator removal procedure in WSM, Section 412-00 to separate the climate control
housing for blend door lubrication. Only perform Steps 1-7 of the removal procedure. It is not necessary
to remove the evaporator core.
NOTE: Both the top and bottom (if equipped) temperature door actuators will need to be removed
from the climate control housing to allow for removal of the temperature blend doors for
lubrication.
3. Remove the temperature blend door. (Figures 2-4)

5. Reassemble the temperature blend door halves and install back into the climate control housing. Make
sure the temperature blend door support half is aligned using the dowel pins. (Figure 8)
Figure 8 - Highlighted area shows temperature blend door assembly properly installed back into the
climate control housing

6. Reassemble the lower half of the climate control housing and perform Procedure A when installing the
temperature blend door actuator(s), cam(s) and cam follower(s). Refer to WSM, Section 412-00,
Installation procedure.

NOTE: F-150 vehicles have a seal near the thermostatic expansion valve (TXV) that may be
damaged/crushed if the climate control housing is assembled improperly.
7. Reinstall the climate control housing into the vehicle. Refer to Workshop Manual (WSM), Section 41200.
