High beams/FTP failure

[Boozer76]

I posted this in the 6.0 General forum and realized that probably wasn't the right place, so I'll try here. I noticed my high beams are not coming on the other night. When I turn on high beams the low beam lights turn off and I have nothing. The flash to pass does nothing at all. The high beam indicator in the dash does not come on for either FTP or high beam. I tested the fuse for continuity and it was good. Any thoughts?

Hey Boozer, I just found this thread with the search.

I hoped on here trying to resolve the exact same problem.

Both headlamps are known to be good.
Low beams work fine.
Flash to pass leaves lows on with no switch to highs, and no indicator.
Flipping arm back for high beams shuts the lights down completely, with no indicator.

I swapped out the switch with a known good one, and nothing changes (ruling out a faulty switch).

Fuse 30 looked good, and a swap made no differance.
I have nothing in the fuse 16 slot (no wiring to the slot).

I was hoping to find a schematic to use.

I'm working on a 2001 F250SD XL 4x4 (sealed beams).

If nothing else, you gotta bump.

Bump, any solutions?

I have the same problem. Any solutions? There has to be a relay that I'm seeing somewhere I have checked and changed everything else.

Fatgirl I sent you a pm with a diagram.

I got your pm. I read in another thread that harness just can't handle "hot" bulbs and that may be my issue as well I'm looking into the heavy duty harness.

You'd be better off doing the relay mod where you put a relay out by the back of your headlights since the switch is the weak part of this.

Ah hell my husband is the electrician I'm the um well muscle

Well here's what the diagram looks like if you where to do it. You can go get the relays from any auto parts store.
