Welcome, I'm Chris (aka Moose) I'm an independent contractor here at Just Answer.
When you say dash lights are you referring to the instrument cluster alone or everything on the dash that should illuminate at night with the headlights on?
Thanks for asking your question and letting me try to help you.
EVERYTHING ON THE DASH INCLUDING CLUSTER
At the headlight switch what is the voltage on the pink wire?
Headlights on what is the voltage on the gray/Black wire?
Is the BCM L fuse in the center console fuse block good?
These will tell me if the switch or BCM is to blame.
If you are unable to rate my response GOOD or EXCELLENT now. Please let me know why ( if I need to help more) and when you will be able to.
Follow up/Reply as many times as needed before or after rating.
I like to stay in contact with my customers that appear not pleased, still working on the concern, or have not rated yet. I assume you were not pleased with my help. I hate that you have spent money to get an answer but left not happy. Can you tell me why, or can I help more. If its more help you need just reply and we can pick up where we left off.
