I have a 2012 Fusion SEL that is having a problem with BLIS on the passenger side. When starting the car, the light on the driver's side mirror comes on for about five seconds and the passenger's side mirror only lights up for about a second before going off. The driver's side blind spot warning and cross traffic alert works fine, but I have no blind spot info or cross traffic alert on the passenger side. When you run the system check, it says "Blind Spot Okay" and "Cross Traffic Okay". I took it to my Ford dealer in Columbia and said "they could not replicate the problem and there was no code". I feel like they just ran the system check and said it was fine. You can tell there is an issue upon starting the car as the lights do not stay on the same amount of time on the mirrors. Has anyone else had this issue? Is it the right side BLIS module?
