Having just spent 2 hours chasing fuses and relays for a headlight out, may I suggest pulling the (-) battery cable off the battery and let the car sit for 20 minutes or so and then reconnect the battery. Then check to see if everything works.
I suspect I had a relay that hung somewhere in my system, but I was not able to find it and my DDM did not indicate any problem on the suspect relays. The power off-on sequence cleared my problem.
The only other thing I can think of might be a BCM that'* gone to the dark side.
