Hi Guys! Two Issues, any help would be greatly appreciated!

1.My rear dome lights work when manually turned on. They do not come on when the door is opened. However, the front dome lights do. Any idea on this?


2.The lights on my side mirrors turn blink when using the turn signal, and when hitting the lock/unlock/remote start buttons. They do not work when driving around with my head lights on.

Please send me any advice you may have. Thanks in advance!!

 

I had time today to look at the diagrams, but I need to know the model and engine.

 

2013 f250 6.7 platinum

 

On your domelight problem, your problem doesn't make sense as far as the diagram goes. Here's the diagram.

You can see the front dome assembly, the rear dome assembly, and the cargo light assembly are all fed by the same grey/violet wire. How does the cargo lamp act since it's supposed to be hooked to the same wire?

On your mirrors, check that fuse f40, 10 amp. I know they blink when you use the key fob, but I am not sure if they are blinking the parking lamp or the turnsignal bulb. The way these things are wired with the body control module, they could do it either way. Here's a diagram for that.

Let me as this, I am able to remote start my truck with the door open, does that mean anything?

 

Is this a truck you bought from a municipality or some other business had it? Some of your problems only make sense if the wiring or the programming in the computer system was changed on purpose.

 

I would assume it was. It had 177k miles at only a 2013 when i purchased.

So what options do I have? dealership?


Thanks for all the help, thus far.

 

The dealership or someone with a nice scanner could probably tell you more of what is going on. They can look at the network and see the different computer modules talking to each other when you activate the domelights and other stuff. But looking at the diagrams, the domelight problem would have to be wiring I would think.
