Tracked down the problem, thought I'd share for future folks with same problem who search here for answers. First, despite what the Chassis Manual states, the turn signal flasher is not mounted in the fuse panel. The Chassis Manual is wrong. On my rig, the flasher is mounted to the side of a dash support panel, under the dash, left side of the steering column.

The flasher was fine, as was the fuse. Problem was corroded contacts inside the turn signal switch unit (turn signals, 4-way flasher, wiper and washer controls all controlled from this same unit).

I determined good voltage into the switch unit, but no voltage out. I took the unit apart and found green, tarnished and corroded contacts. Completely disassembled the switch unit, cleaned all contacts to bright shiny smooth, reassembled with a liberal coating of dielectric grease, and reinstalled. Unit works perfectly. Not sure what that switch unit would cost, but I'd bet better than a $100 from Ford or a local RV dealer. Money saved for upcoming trip.

Did you have to remove the steering wheel to get at the T/S unit?

My 1995 Chassis Manual states that the Flasher is located at:

LH side of steering column support (C1)

subford,

Your pic and manual are correct. That is exactly where the flasher was found on my unit.

Jerry B,

Fortunately no. There is a two-piece plastic shroud that covers the steering column. If you remove the lower half you can access the two Torx head machine screws from the left that mount the T/S unit to the column. The T/S unit has two molded wire plugs that snap in. There is enough slack in the wires that you can pull the T/S unit away from the column slightly to remove the two molded plugs. The T/S unit itself comes apart by removing five small Torx screws. Just be careful taking the T/S unit apart, a few little floating parts inside and a couple springs.

I sprayed everything with electrical contact cleaner, then used steel wool to clean the tarnish off all contact spots. Very little true wear on the contact surfaces, mostly just green tarnish. Sprayed everything again and let it dry. Coated everything liberally with dielectric grease, and reassembled. Electrically it functions fine, and subjectively, the turn signal lever seems a little smoother with the fresh grease inside.
