It started this past winter season, 2010, after the vehicle is all warmed up and I set the cabin temperature control to a comfortable setting it will get hot by itself as if someone had turned the knob to high heat. When I move it to the "Blue" zone it may/ or may not cool off, from then on I have to keep adjusting it to keep the temperature from beiing to extreme either way. The Dealership needs the Escape all day to remove the Dash and diagnose the problem. There are no codes in memory at this time. I could find no information on removing the dash on my own. Anyone have any ideas? Thank you,

This seems to be a common problem on some Escape and there is a technical service bulletin to resolve the problem which is caused by the blend door actuator. This opens and closes the bend door to regulate the air temperature. Here is the tech. service bulletin. I hope it will help to resolve the problem: A/C - Side To Side Temperature Variations TSB 10-8-6 05/10/10 CLIMATE CONTROL TEMPERATURE VARIATION FROM SIDE TO SIDE-BUILT BEFORE 12/17/2008 FORD: 2008-2009 Escape Hybrid, Escape MERCURY: 2008-2009 Mariner Hybrid, Mariner This article supersedes TSB 09-12-6 to update the Service Labor Time Standards. 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.

Thank you for the info. I will inform the dealership and get the check book ready.
COMMENT by Visitor on April 29, 2011
so is this considered a recall on those parts?
COMMENT by ZeeTech on April 29, 2011
Unfortunately it isn't a recall, only a technical service bulletin. It just informs the tech about how this problem has to be repaired. Manufacturers won't like to issue a recall on problems - unless it's a safety issue which could cause accidents. Zee
