I recently installed a factory cruise control kit in my 2003 E350 cargo. I completed everything except reinstalling the airbag, and then took the van for a drive to ensure the system worked. Which it did! However, after I reinstalled the air bag, the airbag light comes on. And now the cruise doesn't work. I shut the van off and tried it a few minutes later. Now the airbag light only comes on for a second when the truck starts and then shuts off. But the cruise does not work.

Any ideas? I've heard conflicting opinions on whether or not there is a fuse for the cruise. Seems like there should be, but is there? If there is, does anyone know where it's located? (under the hood or on the firewall?).

Any guidance is appreciated!

Located the cruise control fuse. It was good. Any ideas?

What do you mean by a factory kit? The factory doesn't use kits for anything. Since you didn't describe what you installed, or how you determined that it was working, or post any pics of it, I'm not sure what help can be offered.

Did you install an electronic servo, or a vacuum servo? A SCCD switch? A steering wheel? A clock spring? Did you use a diagram that looked like these?



More info about the van would help, too.

My apologies.

By factory kit, I mean a brand new factory steering wheel, brand new factory clockspring, brand new factory wiring harness, and a brake switch... all of which came with a ford installation guide... in a kit.

I determined that the system was working by driving it down the road and engaged the cruise. The van held speed when I let off the accelerator. All cruise functions worked. The lights on the buttons even lit, as they should.

The van is a 2003 E350 PSD cargo.

So no servo? When you post pics of the installation instructions, I might be able to help more.

I recently bought a NOS partial cruise control kit, it was missing the clock spring but everything else was included. There is no servo.
Included in the kit was the directions and parts list here is the picture I just took for you.
Apparently once you connect the clock spring, brake safety switch and obviously the cruise control steering wheel the computer in the van will automatically detect and start working.

As for the problem at hand, I've got no clue... sorry

I contacted the place where I purchased the kit. They seemed to think that the clockspring may have died. So they shipped me a new one. Before I installed it, I checked for continuity on the brake switch at the switch itself and through the wires that go through the firewall. It all checked out.

So I removed the clockspring and installed the "new" new one. Fired the van up... no airbag warning light. Figured that fixed it. Took it for a drive.. nothing. Cruise still does not work.

I'm stumped.

There is no cruise servo on diesels. There is no throttle plate to pull open, so the servo wouldn't do anything. The cruise works by controlling the fuel injected into the engine. It's all electronic.

You're kidding, right? What have you asked that I or someone else haven't already answered?
