2004 Ford Expedition 5.4L V8 Eddie Bauer : electrical troubles. Could you please help me ?

[Viko]

Hi guys !

I'm living in France (sorry for my bad english ) and I have some electrical troubles with my Ford Expedition : dashboard backlighting and rear parking lights no longer work. Fuses and relays are OK.
Have you got some information regarding these troubles ?
Thank you so much in advance for your preicous help,

Cheers,
Virginie

The only thing the two have in common is the main headlight switch itself.
Here's a link to download service manual diagrams for the electrical system if you want to use them.

Thank you so much for your feedback.

I changed the switch but all the troubles are still here.
I thought of the instrument cluster. Do you think that it's a good idea ? Do you know if my model needs a reconfiguration of the dashboard (thanks to a toolkit) if I changed the instrument cluster ?

Thanks again for your precious help,
Cheers,
Virginie

Have you checked the bulbs ? Like with an ohm meter for continuity ? Or did the instrument lighting all of a sudden quit ?

If you need instrument cluster bulbs you can replace them with LEDs pretty easy. Are you getting 12v at the parking light sockets ?

Hi and thanks again for your precious help

Parking light bulbs OK
No 12v at the parking light sockets

Did the instrument lighting all of a sudden quit --> yes !
