They also have a cheaper version in the "Mileage Plus Electrical" line, but it only has a 1-year warranty vs. the 3 year for the Echlin. The Echlin is about $15 more ($57 vs. $71), but based on CarringB's suggestion and the additional warranty term I went with the higher-priced one.
The "multi-function switch" (aka turn signal stalk) is pretty notorious for going out. This is one part where you're better off with a Napa Echlin replacement instead of a Ford replacement. Any fleet with older Fords will probably have boxes of bad switches. Unfortunately the diagnostics procedure for testing it is "replace with known good part".
BTW - are you sure you checked the right fuses? The ones under the hood only do trailer lights. The ones under the dash do the van lights.
I also am have a similar problem with mine. It is a 1997 E-350 Econoline. Flasher is working and I checked all fuses and relays under hood as well as under dash. One brake lamp was not working so I bought new turn lamps and brake lights thinking that was the problem but only one brake lamp was blown but brake lamps are working now. Still no turn signals. Tested continuity at flasher relay and when i push the turn switch or hazard switch i have power. Could that still be the problem with the multi-function switch or loose connections behind dash?
Same symptoms on my 1998 E250 a few years ago and it was the multi function switch. Pretty easy to replace. I used the NAPA Echlin one, but one thing I don't like is that it sits pretty close to the steering wheel compared with the stock one, and sometimes I hit it into high-beam mode by accident.
Well it's odd now the blinkers are working but brake lights are not working? I feel very confused now. Wouldn't those be on separate lines? I don't think the brakes and blinkers would be connected. So is it possible I have loose connections under the dash somewhere? I would love for it to be the multi switch and I could deal with bumping it into high beam by accident but I don't think it is that since they are working this morning with the brake lights not. I don't know what is going on.
