The panel gauge lights (speed lights, stero lights, AC lights, etc) in my 96' ES300 go off when I turn on my headlights. If the headlights are off, the panel gauge lights work just fine. Also, the "ELC PWR" warning light has come on. The relevent fuses were examined, and all appear to be in good condition. The overhead dome light is also working.
Any thoughts out there?? :)
