Hello and thanks for using justanswer.com
Remove the steering column covers and look at the back of the headlamp switch. You may find one of the wires broken off the solder causing the problem. Let me know.
Go to the BPM connector and supply battery voltage to pin 28 and 54 to see if the tail lights work. Then go to pin 16 to see if we have ground with the switch on.
Are you sure you replaced the BPM with the same exact part number and programming suffix.
I really am leaning towards the switch as I think there was an error int he wiring diagram as I looked through my notes to see but I cannot find what I was looking for. We need to make sure the suffix is the same. That is the three numbers at the end. It is on the VCATS label in the trunk in the spare tire well.
