2008 ford E350 van tail lights won't turn off. It's definitely not the brake lights.

SOURCE: No turn signals, hazards or brake lights

replace the turn signal switch in the steering column

SOURCE: Tail Lights & Brake Lights stay on even when car is turn off

the plastic round stopper most probably broke that is were the stoplight switch sits when not depressed easy fix find a washer small enough to block the hole were the original plastic stopper was making sure the washer aligns to the brake light switch and secure washer w/ zipties hope this helps.

check the fuses and relays under the hood next to the battery. if they still dont work it might be in the wiring or if it has a tow package it might be in the trailer wiring

SOURCE: 1992 ford ranger =no tail lights,,,,brake and turn signals work

try turning your lights on.....

You have to remove the upper applique to remove the tail lamp, it is the trim panel above the lamp. I think it is held in place by two nuts/bolts but not sure. You have to have the rear doors open to remove it
