Have your buddy replace the drivers side lock switch! I had this issue in mine (possessed while driving and parked), and the hubby replaced the switch (around $20 through dealers) over a year ago. I had absolutely no problems with possessed locks from the beginning of Feb of 2011 until the end of January 2012. (Can't tell you about beyond Feb 2012, because the car's been parked b/c of a bad engine knock since then, but the hubby replaced the same parts in 2 friends of mine's cars, and neither of them have had more problems either.)

I think it took the hubby MAYBE 15 minutes to tear my door panel apart, replace the switch, and put the door panel back together.

I suppose it could be the BCM, but have him just replace the switch first. If it doesn't work, yeah, he's out the $20, but if it DOES he will save so much money. I'd seriously be almost willing to bet my next paycheck that it's just the lock switch. (And I get paid every 2 weeks and have a bonus on my next pay, so it's a pretty decent pay check! LOL!)
