Hoping someone can give me some suggestions. My 2006 Fusion's front, driver side turn signal does not work (both when the turn signal is on, and the hazard lights are on). The rear signal works fine. I have swapped the driver side and passenger side bulb, and it works fine on the passenger side only. I have also swapped the sockets that the bulb goes in, same result... works fine on the passenger side, doesn't work on the driver side.  

sorry to let you know..   all the lights are controlled by the ECM/bcm.. via CAN system...  controller area network..  the switch sends a request to the ECM/bcm asking it to activate the circuit..


it will take a CAN enabled scan tool... to diagnose the possible problems with the communications system between the parts..    or to replace the modules..


there will probably be a trouble code for it stored in the ECM/bcm..


but it still could be something simple.. like a loose connection..  a bad solder joint on the logic board of the light ... if they are accessible..

would you like me to post some articles on the CAN system???  so you can learn about all the items that are drive by wire...  

Have you found out yet what caused this? My wife's 06 Fusion is doing the same thing. Thought it was just the bulb, changed it, checked all fuses. ?? I really dis-like wiring problems! Any help would be great!  

find an OBD2 scan tool that is CAN enabled....... that displays live data .. not just codes....



i will look up more info later tonight...

you might need to subscribe to an electronic repair manual data service...

alldatadiy.com

or

eautorepair.net

both have the repair info... pages and pages and pages of testing...  

i went over to autozone.com... they cover some of the repair info for the 06 and 07 fusions..  but most of its not active yet...
