HI. Just got a 97 LS Rodeo and have a light problem. I have head lights, high and low beam. Have turn signals and 4-ways. Have rear center top brake light. When I turn on the lights I only have front left parking light and headlights. Also, no brake lights except the top center one. Fuses are all good and bulbs are good. Is there a ground somewhere that I need to check. Thanks.
