Question about 1999 Ford F150 Regular Cab
I need a wiring diagram for a 1999 E150 Sharrod Conversion Ford van. And/or pointers or suggestions where to look and how to find the problem. After the van sits for a time something in the electrical system shuts the whole system down. Even the door locks don't work. When you bump the power seat button on the driver's side, the whole system comes back up and works untill the van sits for any where from a couple of hours to a couple of days. It seems it's only that driver's seat power button that will bring it back to life. The other day, the driver's seat button would not work, so the van would not start. Several mechanics have looked at it and are stumped. Also, as a person is driving it, dome lights will come on and go off at random, for no apparent reason. And doors will lock and then unlock at random, for no apparent reason. I know there is an explanation here besides a ghost. Please help.

SOURCE: Electrical system shuts off.
i have a theory,have you tried replacing the door ajar switches,one might be bad,the computer might be seeing a load on the battery for a while after vehicle shut down,and because of this the computer does this to shed loads so the battery is not killed,or the problem could be the GEM module which controls all the power,its actually part of the fuse box and would need to be replaced as a unit but a little exspensive,so i would try the door switches first,hope this helps
