Sounds more like you need to check the headlamp switch-start here

Have already checked the headlight switch. The chime for headlights on stays going when you take the key out. The same when I unplug the headlight switch. It is an intermittent problem. It started one night on my way home after stopping at a store, when I left the store I had no dash lights. I kept messing around and they just came on. Didn't think anymore about it then they just went off again. Stayed off a couple of days then just came back on again. It has been like this off and on for about a month, just never know when they are going to work or not. I have thought about the BCM going bad, and wondered if that might coincide with the problems I am having with the van bucking, but I can't connect the two.

Did you ever get this resolved? I have the same issues. I ordered a new BCM & had the dealership program it but still the same issues. If you did get it fixed do you mind sharing what you did to fix it? Thanks.
