95 F150 No brake lights, turn signals or hazards

[carbdford.com]

Ok.. I got my truck running only to find that I have no brake lights, no turn signals and no hazard lights. I was told it was probably the signal arm as they go bad and can cause this. I tried putting another one on it I had in the garage from a cougar (the turn signal plug fit but not the headlight/wiper plug) but it still did not do a thing. My parking lights will come on and everything else seems to work. I have checked and re checked all the fuses. Anyone have a clue what else could cause this?

The turn flasher and hazard flasher get there power from different fuses and different wires. The brake lights get there power from the same fuse (#13, 15Amp) as the hazard flasher. Left and right lamps and indicators get there power form different wires from the Multi-function Switch.

You can try jumping power to the LG/W wire (wire #3, pin #8) or the W/LB wire (wire #2, pin #5) leaving the C231 connector at the Multi-function Switch.
If the lamps light and you have power at the LB wire (wire #44, pin #1) and
you have power at W/R wire (wire #385, pin #4) of the C231 connector at the Multi-function Switch then you have a bad switch.





I think it is still the Multi-function Switch, change it with the right one.

I have the same issue with my 2002 F150 supercrew - No turn signals, hazard or brake lights.

I'll replace the Multi Function Switch.

Before replacing anything, test:



If it doesn't have power going into it, replacing it won't help. Use your owner's manual to find which fuseS it needs. There are fuses under the dash AND under the hood.
