ISSUE
Some 2008-2009 Escape, Mariner, Escape Hybrid and Mariner Hybrid vehicles built before 12/17/2008 may exhibit intermittent or erratic side to side temperature difference and/or temp fluctuation from the climate control vents. The concern may be with the temperature blend door actuator.
ACTION
Follow the Service Procedure steps to correct the condition.
SERVICE PROCEDURE
1. Remove temperature blend door actuator(s) per Workshop Manual (WSM), Section 412-01.
2. Inspect the 5 digit manufacturer's date code on the temperature blend door actuator. It will be the last 5 digits on the second line of manufacturer's data. The first three digits equal day of year. The last two digits equal year. (Figure 1)
a. If the part number is 8L84-19E616-EA and the date code is 30708 or lower - replace the temperature blend door actuator assembly.
b. If the part number is 8L84-19E616-EA and the date code is 30808 or higher - reinstall the actuator and continue with normal diagnostics per WSM, Section 412-00.
c. If the part number is something other than 8L84-19E616-EA - reinstall the actuator and continue with normal diagnostics per WSM, Section 412-00.
NOTE
IF THE VEHICLE IS EQUIPPED WITH DUAL AUTOMATIC TEMPERATURE CONTROL (DATC), AND EITHER ONE OF THE ACTUATORS EXHIBITS THIS CONCERN AND HAS SUSPECT DATE CODE, THEN REPLACE BOTH RIGHT (RH) AND LEFT HAND (LH) ACTUATORS AS A SET.
