2005 Chevy Trailblazer. We recently had the gas gauge fixed and a sensor for emissions fixed. In the past I have had my headlights dim and brighten along with the lights on the dash, but it only lasted about a mile. Today it did it for 30 miles, same thing dim and brighten inside and out. I think people think that I am flashing them, I am not sure how noticeable it is to them, but to me it is terrible. Any suggestions?????
You need a new altinator if ur head lights dim and u are loosing power!!
