THE INSTRUMENT PANEL AND SHIFTER LIGHTS ALONG WITH THE DIMMER FOR THE CLOCK, RADIO, AND OTHER INTERIOR LIGHTS STOPPED FUNCTIONING YESTERDAY. THERE HAVE BEEN SEVERAL TIMES THE LIGHTS BLINKED OFF AND BACK ON BUT THEY ARE COMPLETELY OUT NOW. AFTER RESEARCHING SEVERAL FORUMS (EX. HTTP://CHEVROLETFORUM.COM/FORUM/SONIC-AVEO-NEW-11/DASH-LIGHTS-AVEO-20707/), I FOUND OTHER PEOPLE WHO HAD THIS SAME ISSUE. IT SEEMS THERE IS A DEFECTIVE PART IN THE ENGINE FUSE PANEL THAT CAUSES THIS ISSUE. THIS COULD BE A MAJOR CONCERN TO MANY DRIVERS BECAUSE YOU CANNOT SEE ANY OF THE DASH INSTRUMENTS INCLUDING THE SPEEDOMETER, GAS GAUGE, TACHOMETER, AND TEMPERATURE GAUGE. MANY SUGGESTIONS TO FIX THIS ISSUE WERE TO REPLACE THE PART, BUT THE PART IS NOT AVAILABLE THROUGH THE DEALER OR ANY PARTS STORE. ANOTHER WAY TO FIX THE ISSUE WAS TO TAKE OUT THE PART AND JOIN ALL OF THE WIRES TOGETHER THROUGH SOLDERING OR A CONNECTOR BUT I THINK THIS SHOULD BE SOMETHING THAT CHEVROLET FIXES. *TR
