Do the tail lights come on with the head lights

Check 20Amp LP Park Fuse in Underhood Fuse Block (mounted to right strut tower) Check 15Amp Tail Lic. Lamp Fuse In IP Fuse Block.

1- faulty light switch
2- faulty shut-off timer
3- faulty ignition switch

Sounds like a fuse problem. Find the fuse box for the lights and replace the one that is for head &tail lights

Yes it sounds like the switch is stuck in the park position.
You could pull the harness plug for the switch and check the circuits with a meter, or replace the switch.

Hello,

Follow this steps below,

Tools:

• 8 mm Socket with Extention
• Flat-Head Screw Driver
• Piece of Cloth

Step 1:
Open the Tail Gate and you will see two tabs on the inner side of the tail light.

Step 2:
Using a Flat Head screw driver, pry open the two tabs. This will expose the 8mm bolts that are holding the tail light.

Step 3:
Using a 8mm socket unbolt the two. Using a flat head screw driver, pry the tail light out. Make sure you use a piece of cloth so you do not damage the paint on the side.

Step 4:
If you are using this process to change light bulbs, then you can just go ahead and swap the bulbs. Otherwise you can just take the tail light out by removing the harness.

Take care.

The switch is bad, it can't be serviced, it has to be replaced

the plate and tail lights are on the same fuse you can check that fuse and the dash light fuse with a test light,
but i'm pretty sure your head light switch is the problem,

ck rear tail light sockets for cracks broken wires. and terminals in connectors are not touching

Check the bulbs for burnt filaments. Take a multimeter and test your feeds and grounds at each socket. Possible multifunction switch failure. The switch that works your head and tail lamps.

have you checked the bulbs, wiring, and plugs in the trunk for corrosion? have you checked the tail light or marker light fuse. the headlights and taillights are on separate fuses. mike
