They theorize that flashing the BCM with calibration files from a car with the heated mirrors might work. We would need to find a car built at near the same time as mine and with the same options + the cold weather package. They didn't want to do this as flashing the BCM takes a long time. Also no one knew if flashing with another car's files could screw up my car or its conversations with Ford computers when it's in for other maintenance work.
To even try the flash I would need the help of a friendly mechanic and dealer in the CT area.
The BCM seems unfortunately the heart of the car. It is the central hub to all other modules and screwing it up would be very bad.
If there's anyone on the forums with greater knowledge as to how these things work your help would be greatly appreciated.
So you're saying that even though the mirrors are plug and play, they won't heat up due to the fact their not coded into the BCM? Fail :(
