SOURCE: need to locate the relay 303 fuse on a 2003 Ford

Here is some information about your problem. If you go to motorcraftservice.com you may be able to see the Owners manual. Starting about page 249 are the fuse and relay Sections. From what the Manual shows, the Relays from 301 to 305 are part of the fusebox.

If you want to service this yourself, go to QCComponents.com. Their part# is 20Z0A11B for the orignial Omron F8VF-BA Relay that is in there. Some people just unsolder the old and replace with the new and solder it in.

This Relay is for your Fuelpump, Fuelpump monitor, and the PCM. It is at location 303.

I would recommend Browsing the F150 and FourWheeling Forums for Technical information about this part and installation. I hope my solutions are very helpful to you.

SOURCE: main relay fuse # for

Not sure as to what you want. When some people say ignition they are talking about the starting system while others are talking about the coils and stuff. To be on the safe side I gave you diagrams and descriptions for all. This should be in your owners manual if you have one. If you don't and would like a copy, you can email me at csautomotivecars@att.net with your make, model and year and I will be happy to email you a copy. Don't worry no cost. I hope this helps and good luck.

What is and where is the body modulator on 2003 ford expedition


Check above the fuse panel on the drivers side. I am not sure what year they changed the GEM Modules location. They were known to get wet and fail. Not sure if yours is in that category. I would have to check at work.

What fuse is for the drivers door keypad an a 2003 expedition


In the fuse diagram for the 2003 Ford Expedition, a fuse is not indicated specifically for the "Door Keypad"; However it does show which fuse is needed for the Door Lock and Door Lock/Unlock Relay. Fuse location 30, Fuse amp rating 30a.

If you already have a manual, you will find this information in the table of contents under "Roadside Emergencies" fuses and relays.

If you do not have a user manual, you can download one at http://www.motorcraftservice.com

On the menu to your left, click on "Owner Guides".
In the drop down menus click on the year and the model.
Below those drop down menus is another drop down menu, click which Owner Guide you want. I clicked on "1st printing", as well as "2nd printing". The fuse info was the same on both.
