Rear running Lights

[nboeger4]

So guys I have 3 little lights that were installed in my tailgate when I bought my truck. I noticed the other day none of them were working. I figured they all burnt out. Installed new lights and still there not working. After looking some things over the rear running lights in the brakes aren't working either. All of the front, interior, and cab lights are. I have checked fuses with no luck. Any ideas?? I need some help on this one.

Check the connectors under the bed. They are behind the rear bumper on the drivers side frame rail. If those are connected you'll have to start tracing wires and checking fuses. But as far as I know all the running lights are on the same fuse so if the front ones work then the fuse Is most likely still good.

I had a truck come into the shop a few weeks back (Ford diesel tech) and I myself checked the simple things such as fuses and wires. Most people dont know a lot of the lights that we have on our truck also run into the multifunction switch (wipers turn signals and high beams) I'd look at replacing this if you can't find any other sources.

Can you go a little more into detail about this switch?? Haven't heard of it.

I believe he is referring to the lever that controls the signals, wipers, washer, and high beams that is located on the side of the column.
