Just bought a 2017 F250 Lariat and noticed on the drive home last night the roof clearance lights are not on. I don't think there should be a switch so maybe it's a fuse or the harness was never plugged in. Any help on which fuse or harness location would be great. I did look behind the inside passenger side windshield trim(where the handle to help get in is) for a connector but didn't see any there.

 

Yes, there is no switch, they should be on with markers. I would get the dealer to address, as they likely have to check fuses and then check plugs up under the headliner are plugged in.

 

Any idea which fuse it might be?

 

Could the manual show fuse locations?

 

yup.......

 

If there was one labeled roof clearance lights that would make it easy. I did see auxiliary lights which I checked but being a 40 amp fuse makes me think this isn't the right one.

 

Stopped by the dealership and they found the harness behind the dash(glove box area) was never plugged in.

 

Glad it worked out for you!

 

FSRBIKER,

Thanks for posting this. I just brought my new SuperDuty home and noticed my roof clearance lights are not working as well.

I guess I'll look behind the dash before taking the time for a trip to the dealer.

Thanks for sharing.

 

There is supposed to be a plug on the passenger A pillar but I didn't see one there. The other plug is behind the glove box which looks simple enough to release and swing down to get to the plug.

 

Thanks for the additional info.

I found a YouTube video of a guy showing the plug at the bottom of the A pillar.

I did find the plug in the pillar. It's under some white foam after removing the A pillar cover. It's way down there but just at the base of the cab near the windshield. That plug was attached fine. It has purple/black & purple/white wires in it.

I did also pull out the glove box to allow acces to the many plugs and control modules. While there were two plugs just capped off, I could not find any location they intuitively plugged into.

so I guess it's off to the dealer at lunch tomorrow.

 

Well,
After four days at the dealer they called and said "they can't fix it". They have tested everything to "the end of their abilities" and don't know what's wrong. They said everything is plugged in at the A pillar and behind the glove box. The only option now is to remove the head liner "which is above their pay grade". I can't believe one of the largest Ford dealers in Birmingham can't fix some lights. They didn't suggest to keep it longer and work on it further, they just gave up.

So now I have to give up the truck to another Ford dealer next week.

 

above their pay grade??? Wtf??? I can pull down the headliner in less then 30 minutes (the front to gain access)

 

Electrical problems in my experience can be very frustrating to trace down.

The general mechanics in my world have always expressed being conflicted about justifying the shop time needed to trace down electrical problems. I can identify with the service rep on how hard this can be.

That being said, good grief, a Ford dealership should be able to handle tracing out something as simple as cab lights.

If I were given the "I give up" response from my dealer I would look for a dealer with a higher level of skill in the service department. My grandson and I could certainly pull a headliner. It might be best to be with another dealer should something really significant go wrong with the truck in the future.
