When applying brakes and using the turn signal (blinker), the lights on my A/C display blink in unison with my turn signal. Oddly, this occurs only when my headlights are turned OFF. If the headlights are ON, it doesn't happen. Any clues to why this happens and how I can fix it? Tech at the dealership said it may be developing a short and they would have to remove a significant part of the inner paneling to troubleshoot it.
Thanks!

Yeah, something's definitely shorting out. The tech is right, to trace all the wires they'd have to disassemble the instrument panel and dashboard.
