2004 Ford Econoline e-350 Van Electrical System	Sign In

Hi guys,

I have a 15 Passenger for van (for my band) and there's a major problem with the electrical system. A couple weeks ago everything flash off and then on while I was driving, then no issue for a couple weeks. Then on our way to a show everything turned off and stayed off for couple hours. On the way back, mid trip it all turned back on. We weren't "doing" anything but driving when this happened. Now everyhting is off and it seams like they are off for good.

I took it too a mechanic who I don't entirely trust and after working on it for two days he said it needs a new wiring harness. I know a lot about electricity and soldering... it seams to me like one loose wire but he wanted $1100 to fix which I cannot afford.

Currently the following DO NOT hasve power:
Stereo
All Gauges (Gas, Speedometer, Tach, etc)
Mileage/Trip counter
Vanity Mirror Lights
Interior (overhead) lights
Auto Windows
Auto Mirrors
Birghts

The following have power and are working fine:
Regular headlights
Dash lights (gauges light up)
Power Locks
Wipers
Cigarette Lighter
Emergency blinkers
Overdrive switch light
AC/Heat
Wiper fluid

Any ideas what the issue could be? Can I fix this myself? THANK YOU SO MUCH FOR YOUR HELP!

Guess: It doesn't need a whole wiring harness! There's no doubt a fuse underhood or fusible link that enables all those things. Test things and path of power with a test light for where it stops.

Once but probably happens more than I've witnessed the block where all wiring passes thru firewall was the issue and didn't make a good connection to interior fuse box,

Fords have also been known to get carbon-tracked inside the ignition switch and create electrical gremlins. Check near the box first as tom said, and if all good there check out that switch.
