2003 ford expedition power door locks dont work third row seating no power radio doesnt shut off when you open door and the automatic light setting isnt working either

try checking your battery connections. also check fuses and relays.

Yep already did all that fuses and relays all good battery connection good too

Sounds like a lot of wiring connected to the door. Check where the wiring goes through into the door and see if anything is broken or pinched off.

My 04 expedition is in the shop now for the exact same thing. My 3rd row seats won't raise. Door lock on door won't work, keyless remote won't open door, dome light doesn't come on when door opens, automatic head lights don't work, only manual head lights work, radio doesn't ever shut off unless you push power button off Has anyone found a solution? Mine is in shop and mechanic told me it's wiring harness, they are stripping every wire to test it.

Pamela I'm having the exact same issue.. What did they find for u?
