This may be due to a poor electrical connection at the blower motor speed control. If the blower motor speed control is determined to be the causal part, replacement of the electrical connector pigtail harness (14S411) to the blower motor speed control is also recommended to avoid repeat repairs. Refer to Wiring Diagram, Cell 5 for recommended splicing procedures. Refer to Wiring Diagram, Cells 54/55 to obtain the service pigtail connector part number.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2019/MC-10156877-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2019/MC-10156877-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10156877","components":[{"id":"electrical","name":"Electrical system","parent":null},{"id":"engine","name":"Engine","parent":null},{"id":"equipment","name":"Equipment and accessories","parent":null},{"id":"hvac","name":"Heating and air conditioning","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"FORD","model":"EXPEDITION","year_from":2009,"year_to":2017,"match":"exact","vehicle_ids":["2009_ford_expedition","2010_ford_expedition","2011_ford_expedition","2012_ford_expedition","2013_ford_expedition","2014_ford_expedition","2015_ford_expedition","2016_ford_expedition","2017_ford_expedition"]},{"make":"FORD","model":"EXPLORER","year_from":2011,"year_to":2019,"match":"exact","vehicle_ids":["2011_ford_explorer","2012_ford_explorer","2013_ford_explorer","2014_ford_explorer","2015_ford_explorer","2016_ford_explorer","2017_ford_explorer","2018_ford_explorer","2019_ford_explorer"]},{"make":"FORD","model":"F SUPER DUTY","year_from":2008,"year_to":2008,"match":null,"vehicle_ids":[]},{"make":"FORD","model":"F-150","year_from":2009,"year_to":2014,"match":"exact","vehicle_ids":["2009_ford_f-150","2010_ford_f-150","2011_ford_f-150","2012_ford_f-150","2013_ford_f-150","2014_ford_f-150"]},{"make":"FORD","model":"FLEX","year_from":2009,"year_to":2019,"match":"exact","vehicle_ids":["2009_ford_flex","2010_ford_flex","2011_ford_flex","2012_ford_flex","2013_ford_flex","2014_ford_flex","2015_ford_flex","2016_ford_flex","2017_ford_flex","2018_ford_flex","2019_ford_flex"]},{"make":"FORD","model":"MUSTANG","year_from":2009,"year_to":2014,"match":"exact","vehicle_ids":["2009_ford_mustang","2010_ford_mustang","2011_ford_mustang","2012_ford_mustang","2013_ford_mustang","2014_ford_mustang"]},{"make":"FORD","model":"TAURUS","year_from":2010,"year_to":2019,"match":"exact","vehicle_ids":["2010_ford_taurus","2011_ford_taurus","2012_ford_taurus","2013_ford_taurus","2014_ford_taurus","2015_ford_taurus","2016_ford_taurus","2017_ford_taurus","2018_ford_taurus","2019_ford_taurus"]},{"make":"LINCOLN","model":"MKT","year_from":2010,"year_to":2019,"match":"exact","vehicle_ids":["2010_lincoln_mkt","2011_lincoln_mkt","2012_lincoln_mkt","2013_lincoln_mkt","2014_lincoln_mkt","2015_lincoln_mkt","2016_lincoln_mkt","2017_lincoln_mkt","2018_lincoln_mkt","2019_lincoln_mkt"]},{"make":"LINCOLN","model":"NAVIGATOR","year_from":2009,"year_to":2017,"match":"exact","vehicle_ids":["2009_lincoln_navigator","2010_lincoln_navigator","2011_lincoln_navigator","2012_lincoln_navigator","2013_lincoln_navigator","2014_lincoln_navigator","2015_lincoln_navigator","2016_lincoln_navigator","2017_lincoln_navigator"]},{"make":"MERCURY","model":"SABLE","year_from":2008,"year_to":2009,"match":"exact","vehicle_ids":["2008_mercury_sable","2009_mercury_sable"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
