Hey all. I'm a "new" Expedition owner. She's a 2003 XLT 4x4 with 160k miles.

Today, when I stopped at Auto Zone to pick up a new door lock actuator, the instrument cluster, radio and power windows stopped working. For the first time ever (in the 1 week of ownership) the radio went off when I turned off the engine. This had me wondering what was up because the radio stays on and won't turn off by itself.

When I got back in the car and started her up, the instrument cluster was dead. The radio wouldn't turn on. And the power windows wouldn't roll down.

I drove her home and on the way, the airbag light started blinking and then stayed on.

I've done some research and some one suggested removing the negative battery cable to let the computers reset themselves.

This didn't work.

Any advice? I just bought her!!

Thanks!!!

Accessory delay relay with the trailer tow/battery charge relay

i believe this was resolved by the new alternator install when it was a bad regulator, right?

Ive checked the relays and switched the two suggested. Still nothing.

Ive also checked the fuses and they are all good.

But I checked for power at the fuses and 3 have no power:
fuse 450- instr panel
fuse 22 - power windows
fuse 7 - radio

Any ideas?

Thanks

fuse # 22 gets it power from the Accessory delay relay pull the relay and check to see if you have power on pin 30 and then jumper pin 30 to pin 87. you would do this on the fuse block to figure which socket is pin 30 and 87 look on the relay for the pin layout diagram

Sorry... fuse 450 is meant to be fuse 15. I'm outside reading this on a tablet and can't really see the screen.

Fuse 15 is for the instrument panel.

Thanks for the help. Keep the ideas coming!!
