2007 4L, parking lights & dash lights not working; headlights/signals/fog/interior dome and all other electrical working fine.
*Checked: interior fuse panel, parking light fuse & all fuses good.
*Checked: fusable links, all are good.
*Replaced: interior parking lights/head light switch

Was towing a trailer when the lights went out after awhile of being on road. Would think if a short occurred, it would have blown fuse. Any suggestions?
