    Q:
    Where can I find an electrical wiring diagram for both my passenger and driver headlights and my inside overhead lights? I had both my headlights replace a couple of years ago and my driver side has gone out again, I tried to replace the light but it is a shortage somewhere along the way because I should not have to replace my headlight switch every 3 to 4 years.
