Signal Lights Not Working

Before you go crazy chasing phantoms, try this first;
Fill the well around the emergency flasher button with WD40. Work the button up and down until it operates smoothly. Now check your lights and let us know.

If Diagram above is your panel, it uses ATO (plastic) fuses. Ours were glass, so Ford went to a newer style panel. Just looked at the Diagram at 200% and 400%. Do likewise and focus on Fuses 1 and 5. Do the other features they serve work, or not.

Oh, My...Looky Here:

HAZARD FLASHER - 1985 Ford E-350 Econoline (D1FZ13350A)
and

TURN SIGNAL FLASHER - 1985 Ford E-350 Econoline (C5AZ13350B)

These were on a Ford Dealer's parts website. BOTH discontinued. By Ford that is. The auto supply stores'll have them.

Here's Autozone

And it looks like Two-Terminal. This one flashes 1-10 Lamps.

And the Four-Way

Verify any part numbers anybody sends you. What worries me is you say neither flasher system works. Maybe one fuse feeds both, maybe somebody discarded both flashers. Mystery brewing...

Kit, we had an '84 C on '83 E350 and the above was all the chassis fuses it had. Few Fusible Links under the Hood and that was it. Panel above was in the floor pan to the left of where the column passed through the floor mat.

Your '08, probably more than our current '02, has probably 3x the circuits and fuses the older ones did. Especially while they still had carburetors.

OP, First, Belated Welcome to the Forum! You have questions now, but it won't be long before you're giving answers!

You should see either three socket slots in a "C" pattern or two slots in an "L" pattern. If you have a single front turn signal bulb and two rear bulbs (on each side) and do NOT have a trailer or vehicle connected to your coach... Then you need a Three-Lamp version of the "C" or "L" flasher. One bulb each side and then you need a Two-Lamp flasher. Yes, you can get a "Heavy Duty Flasher" that blinks between one and six bulbs. Problem with those is that they flash at the same rate regardless of the number of bulbs. That's good till one goes out. The Two- and Three-Lamp ones blink differently or not at all if a bulb goes out. That warns you to get out and check.

I don't remember if we had a separate flasher for the 4-ways. I don't think so but again don't remember for sure. If Ford's solution in that year was One Flasher, then (at least logically) it'd need to be the HD version.

OK, Upper Left



Told you Memory was Fading...

I pulled up 1985 because it's common as not for the Chassis Year to be one older than Coach Model Year. Builders stock up on chassis at end of Chassis Model Year and build RV's till they run out of them then order more.

I have a 2008 Winnebago Outlook Class C and had a similar problem. I found a 10A fuse blown in the fuse box under the hood. Good luck.

What class of RV is this? A or C? And, whose Chassis it is, is more important for questions like this than whose House is on it. Ford? Chevy? or ______?

You posted in "C" and Ford was predominant in the mid-1980's. Fuse panel to the left of the steering column, inside, should have a little "can" flasher. I think in the lower right corner but memory fades.

You did look infer the front emgine lid?
