thirdgenlxi Posted September 24, 2013 Report Share Posted September 24, 2013 Printable View (50 KB) TSB 11-9-6 WHITE FLAKES OR POWDER COMING FROM A/C VENTS Publication Date: September 14, 2011 FORD: 2005-2009 Focus 2008-2010 Crown Victoria 2000-2005 Expedition, F-150 2007-2012 Edge 2008-2010 Escape LINCOLN: 2008-2010 Town Car 2000-2005 Navigator 2007-2012 MKX MERCURY: 2008-2010 Grand Marquis, Mariner This article supersedes TSB 09-21-6 to update the vehicle model years and Service Procedure. ISSUE:Some vehicles may experience white flakes or powder coming from the A/C vents when the blower motor is engaged. ACTION:Follow the Service Procedure steps to correct the condition. SERVICE PROCEDURE NOTE: WHEN WORKING WITH COMPRESSED AIR AND NUISANCE DUST, THE USE OF DUST PROOF GOGGLES AND A DUST MASK IS RECOMMENDED. NOTE: THE ENTIRE EVAPORATOR CORE SURFACE MUST BE DRY FOR BEST RESULTS. NOTE: WHILE PERFORMING THIS PROCEDURE AND SELECTING DIFFERENT VENT MODES SUCH AS FLOOR / PANEL AND FLOOR / DEFROST, IT MAY BE NECESSARY TO TEMPORARILY START THE ENGINE TO ENABLE MODE DOOR MOVEMENT. Clean A/C Ducts: Remove floor duct trim. Using masking tape, connect one end of the vacuum cleaner hose to the floor duct on driver side. Tape closed all the other floor duct openings. Obtain about 61 cm (2') of rubber vacuum line large enough to fit the end of a small shop air blowgun. Secure the hose to the end of the blowgun using a worm clamp. Close all instrument panel registers. Set temperature setting to full cold. Place mode in floor / panel. Turn on vacuum cleaner. Working with one register at a time, insert the vacuum line down each duct and blow shop air through each duct for 30 seconds. Be sure to close each register before moving on to the next register. Change mode to floor / defrost. Blow down each defroster duct for 30 seconds. Alternate mode door between floor and floor / defrost three (3) times, giving the door time to move between each change. Turn off vacuum cleaner. Clean Evaporator Core: Change mode to full floor. Ensure temperature is full cold. Remove blower motor per Workshop Manual (WSM), Section 412. Turn on vacuum cleaner. Reach into blower opening with vacuum line and using compressed shop air set to maximum inlet pressure of 689 kpa (100 psi) proceed to blow compressed air for a minimum of 5 minutes, utilizing a very slow sweeping action. Blow the entire core face with an up and down motion, then repeat moving from side to side. NOTE: ATTENTION TO THE BLOW-OFF OF THE EVAPORATOR CORE SURFACE WILL DETERMINE EFFECTIVENESS OF REPAIR. Install the blower motor per WSM, Section 412. Open all registers. Operate the A/C system in Max mode with the blower on the lowest setting. Monitor the temperature with a thermometer until the lowest temp is achieved. Switch to vent and monitor the temperature until ambient temperature is reached. Repeat Step 9 three (3) additional times. Switch the blower motor to high speed with the vent mode still selected. white flakes should not come out of the vents. If no white flakes are present continue to Step 12. Disconnect vacuum cleaner and remove tape from floor duct. Reassemble floor duct trim. Blow powder off or vacuum dash board and vehicle interior as required.

fastman Posted September 24, 2013 Author Report Share Posted September 24, 2013 Thanks thirdgenlxi!! Unfortunately, even after this TSB was performed, Im still having new flakes in the car. Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted September 24, 2013 Report Share Posted September 24, 2013 Has the amount/frequency at least gone down? It may take a bit of use to finish dissipating. Even though the TSB implies a thorough "duct cleaning". Quote Link to comment Share on other sites More sharing options...
fastman Posted September 24, 2013 Author Report Share Posted September 24, 2013 Has the amount/frequency at least gone down? It may take a bit of use to finish dissipating. Even though the TSB implies a thorough "duct cleaning". It is a bit less then before, but its still coming out. Especially visible all over the black interior. Dealer said to bring it back anytime. My guess is that they will perform the whole TSB again. Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted September 24, 2013 Report Share Posted September 24, 2013 Maybe you should stand and watch to make sure they do it right! Quote Link to comment Share on other sites More sharing options...
brijamgel Posted January 4, 2014 Report Share Posted January 4, 2014 My 2007 Edge is currently in the shop for the dreaded PCM and COP issue. I haven't noticed this white flake issue, but should I ask the dealership about this TSB while they are replacing the PCM and COP's? Quote Link to comment Share on other sites More sharing options...
