i have two problems my dim headlights will not come on.and when go to put in gas it will flow back word make it seem like the car is full.
how do you fix the heat in a 2002 Chevy impala
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.

You might check all the ground wires going to the headlights to make sure you are getting a good ground.

What are the headlights doing? Is the bulb burned out? Are the lights not coming on at all? Are they misaligned?
