I'm having the same problem with our 2011 Edge Limited with the upgraded sound system. The hazard light "button" (that doesn't actually move) and CD eject have always been frustrating (hard to get to work when you want them to, but sometimes coming on when you don't). Recently, the hazard lights started coming on completely by themselves. One evening, various of my neighbors came to my door three times to tell me that my hazard lights were on while the car was sitting in my driveway. I would go out, unlock the car, mess with the button, start the car, etc. until I was finally able to get the hazard lights off. Then I would lock it up and go back in the house. An hour or so later, someone else would come by and tell me they were on again (with the car locked, and no one in it). The next day, the battery was dead (probably from the hazards being on during the night).
I've looked on-line at Ford parts dealers and ebay, but am having a hard time finding the part I need using the part numbers and descriptions mentioned in previous posts. I would like to take one out of a salvaged Edge Limited and replace it myself (with the new one that has real, moving buttons), but it isn't clear to me if I can just do this and have it work, or if some sort of software update will be needed even if I replace the physical part myself . I'm trying to avoid taking it to the dealer if I can do it myself. Has anyone done this themselves? Can you offer any more advice?
Thanks
Doug
