2002 Buick Regal
My car completely died last night. i had to use the release key switch to remove my keys after trying to start it and not even getting a single light on the dash. The only lights that were on an orange bulb in the headlights. I’ve now gotten the inside power working by resetting and using a trickle charger. Those lights are still on now while charging, what are they? and how do i get them off?
