How do I remove the top of the power distribution box of a 2000 windstar?

There's no relay for the power door locks? Who told you there was? Power flows from a 15A fuse in the underhood fuse box to the right and left door lock switches. The switches move power to the acutuators. This is a low amp system. Doesn't need relays

In your owners manual, 301 and 303 says, not used. All I can do is look at your owners manual for those numbers. The relays for your vehicle in my database aren't numbered that way.
fleet.ford.com should have your owners manual, if you don't have one. It's free to read, online. The top fuse box is from owners manual, the lower fuse box is from my database.

Look in the underhood fuse box-the power distribution center. Likely the cover on the box has labels or diagram for the fuses.

Power distribution box is under the hood on drivers side. Also fuse panel under dash on drivers side, but you have to remove lower (black) panel to access.

It's possible that you need to check the Expedition Owners Manual (pages 161 and next); two locations there...

Passenger compartment fuse panel
The fuse panel is located below and to the left of the steering wheel by the brake pedal. Remove the panel cover to access the fuses.



Power distribution box
The power distribution box is located in the engine compartment.
The power distribution box contains high-current fuses that protect your vehicle's main electrical systems from overloads.



Hope this helps.

Look in your owner manual for the 3 fuse box locations. It is similar to our Lincoln LS.

I am a retired ford dealer electronics tech and the only way to repair this is to replace all the components that are burnt, this means a new wiring harness, the power dist. box is not sold seperate it is part of the ain harness, I know this is not good news, but if you want to keep the car then this is what has to be done to not have future problems.
