“I was driving to work and my head lights went off. I have paid 3 different mechanics to fix this problem and it has only gotten worse. I even paid aamco over 500.00 to fix this and they ended up giving me my money back. And now the whole lighting system pops on and off including back lights and running lights. My back wind shield wiper no longer works and my door ajar light stays on..I like my truck but I don't know how to fix this problem. I work 21 miles from my home and I work night shift. This is dangerous on the highway. …”
