ok heres the problem.
Ive recently installed a new head unit. and after i installed it, everytime i turn on my headlights at night my dash board goes blank. everything on the instrument cluster goes out. I switched out the button to change the brightness of the dashlights and that does work. PLEASE HELP!!! I brought the car to a stereo place and they reinstalled the thing so i know now that it is installed properly. so i dont know what to do. PLEASE HELP!!!!
