Hello everyone,
I installed a new head unit a few days ago. The install went without any trouble. Then the other night I notice that my left side parking lights don't work, front or back, but the right side does. The flashers, brake, reverse, and turn signals work fine, or shall we say come on when they should. Only the parking lights. I backed trace every step I can imagine, even took out the radio, just in case I pulled a wire or something. Nothing seems to work " and NO the bulbs are not burned". All I can think of is that there is a ground loose somewhere..GRRRRRRRRRRR..
anyway any input or help will be greatly appreciated...
