Re: Multifunction switch
You will not be able to take a BCM out of another vehicle and install it in yours, because it will have the VIN of the original vehicle it was in, and it won't match the VIN of yours, and thus there will be communication problems....
Sorry for the confusion of the year and diagram....this is what happens when you jump onto another post....
On a 2008, there is no flasher module, and the directionals and headlights are controlled by the BCM.....
A Tech II scan tool is essential to the diagnosis of the BCM, including inputs and outputs....
Since everything was working BEFORE the accident, how was it determined that it's the BCM and not a wiring problem?
