A blown fuse,you will find the fuse box on the passanger side of the dash board,open the door and their will be a panel covering the fuse box.Pull the panel off and replace the fuse that says REAR PRK LP if its blown..
If all the dash lights are out, it is the switch that is the problem.other wise, you have to remove all the lowre pannels to get at the bolts that hold the dash cluster in.
The dash lights on a Chevy Impala is used to illuminate it during night time driving. There are a series of bulbs spread out throughout the dash to light up all areas.
Owners manual has location of all fuses. Interior fuses are usually on the drivers side of the dash between the dash and door.
they are fused separate but check to make sure someone has not turned your dash light brightness feature al the way to dim
The fuse is blown. They put the dash lights and tail lights on the same fuse so that if you are driving at night the absence of the dash lights will be made relevent to you in order to get your tail lights fixed.
it would be the bulb.
Some things do not have power until a demand is made of them. The dash lights and cruise control are two that work that way.
The same problem happened to me, I l;ost all dash lights on my 2000 impala. It turned out that the head light switch went bad and had a burned terminal on it. All of the dash lights are routed through the headlight switch. The switch costs about $100.00 from GM and is easy to replace
CHECK THE FUSE PANEL DASH & TAIL LIGHTS WORK FROM SAME FUSE
What do you mean by "send electrical waves through the dash panel and radio system?" Do you mean the dash panel and radio lights dim also at the same time? I would check your headlight switch. My 200o impala had a similar problem and once i replace it fix the problem. My 2002 Impala did this also and I thought it was the alarm I had put in. I guess from your results also it wasn't the alarm.
