Did You Check The Fuse Box Under The Hood? If Not, Open Hood, Look Down, Slight Right,, See Box Looking Thing,, Open It..Row Of Fuses On The Left Side Of Fuse Box,, Near The Bottom Of The Row Are The Fuses For The Lights And Others,,, Check ALL FUSES! Not Just The One You Think Your Looking For,,You Just Might Find Others Blown,,,Also LOOK Close,,I Had Some Ding Bat Shove A Cotter Pin In Place Of A Fuse,,That Burned Up The Switch On The Colum And Every Thing Inbetween. Also Check To See If Running Lights Have A Plug In The Trunk Area,,Im Not Pozative On The Trunk Plug Thow... All My Problemes Were From Under the Hood And Dash. Good Luck And Happy Hunting!
