Daytime Running Lights.

[Kober]

All my vehicles have DRLs. On my 2006 RAM 3500 I had to ask the dealer to turn them on via the ECM. My Class C on a 2014 Ford 450 does not have DRLs turned on. Is that something I can do myself? Asking since Ford dealers do not want to touch RVs.

DRL needs to be enabled in the body control module. Will need a dealer or shop that has the equipment to do this

Reach down and turn on the headlights when you want DRL. Beats worming under the dash to find a fuse.

Do an internet search on Ford E450 fuse block diagram/daytime running lights. It might be a fuse that's required to actuate the DRL function. I wanted to be able to disable it on my 2002 Roadtrek (Chevy Express 3500 van), and it was easily disabled by pulling the correct fuse.

Any shop with a programmer for your vehicle should be able to activate automatic DRLs.
