Power driver's seat, pedals and side mirrors do not work

I have a 2004 Ford F150 Lariat. The driver's seat, side mirrors and adjustable pedals do not work any longer. The fuses are fine and I have tested them to be sure. I have read a bunch of different things on internet but nothing seems to work. Do you have any suggestions please?

    Same issue here on a 04 lariat, no driver power seat, petals, or mirrors. fuses are fine, seems to be an issue with the wiring, maybe a short, read a few different thing, factory splice in a Orange w/ green stripe or a short under the seat. Need more details, everything appears to look fine.

Maybe, you can diag yourself with a test light and an ohmmeter. These will cost less at sears than having a dealer diag it. Check fuse 109 in the cab, that's the fuse for the driver's seat module. If that fuse is ok, then check power at the module. It's a little black box under the driver's seat with i think 3 connectors. Back probe the dark green wire at the connector with a test light, you should have power, even with the key off. If not, repair the circuit. Clamp the test light to battery positive and back probe the black wire, if the light does not light, repair that ground circuit. Test the memory set switch by measuring with an ohmmeter points 7 and 2, 7 and 6, 7 and 5 resistance should be less than 5 ohms, if not replace it. If all these tests pass, disconnect the connectors from the module and give 12v to the red and white wire. If the seat moves, have the module replaced at the dealer, it will have to be programmed.

Might want to check the driver's side door sill for a splice that is corroded.

In the SCab, I have seen this closer to the driver's side kick panel, where the hood release is at ( still in the door sill ), on the SuperCrew, I have seen this splice at the back, where the wires turn up the C-pillar.
Here are some pictures from other people that had this problem.

The front, the wire with the bad splice was reported to be a blue w/ White stripe wire.

When it is found in the back, it is a violet wire

If you check the fuses for those items, you will find the fuses are fine, but when you check the switch for the item, there is no power.

It will take some time, but checking for a broken splice, that is not obvious, but the chance is high you will find one in the sea of wires in the door sill.

There are some relays located in the fuse box under the hood.( Drivers side, located directly in front of the power booster for the brakes. open the lid & you will find 2 rows of fuses & 5 relays) you will have to refer to the owners manual for the diagram for the electrical fuses & relays.
