When i turn the switch to parking lights the dash lights and all 4 parking lights come on but when i got to full lights my low and high will come on but my dash lights go off and my taillamps dont come on i have breaklights but not marker/parking lights anywhere around the car. Please help if u can. Thanks

 

Are any of the bulbs out? Start by checking all the bulbs, and replace any that are out. Then check fuses. Once you have done that, try fiddling around with the light ****. Maybe that has gone bad.
