Hello and thank you for using justanswer.

Does moving the dimmer swtich for the dash lights seem to help any? Do you lose taillights when this happens?
Customer: replied 5 years ago.
Have not tried moving the dimmer lights. I'm asking questions on behalf of friends. I'm told headlights are not lost. Not sure of the tail lights.
Expert:  Dave Nova replied 5 years ago.
All lighting is controlled by the BCM (body control module). Most of the time when the lighting malfunctions, it is due to a fault in the BCM.
Customer: replied 5 years ago.
Where is the BCM? Is the whole bash board instrument panel? Can it be replaced by a do it yourselfer?
Expert:  Dave Nova replied 5 years ago.
The BCM is located under the left hand second row seat. The BCM is easiy replaced, but must be programmed by the dealer after installation.
