1996 Ford Windstar battery saver relay

Are battery contacts clean and tight? Take terminals off the battery, clean them well and see if this makes a difference. They may look clean from the outside, but it's the contact they make to the battery posts which make all the difference.

If yes, I believe there is a "Main Relay" which provides power to most functions in the electrical circuits. If this Main Relay is bad, it can result in a dead car as you describe.

I just checked my Hayne's repair manual wiring diagram after I submitted the first reply.

There is a PCM Power Relay. Location is in the engine compartment fuse box.

Ford provides owner's manuals online by going to www. Motorcraft. Com and clicking on the "Technical Resources" link. Download your owner's manual if you don't have it. The picture and location of the relay will be in the "Roadside Emergencies" section.
