The very 1st thing u must do is to have the system scanned for fault codes, this is #1 in the repair sequence, the codes received will give direction to what needs to be repaired,remember this system is completely electronically controlled, all the modules can be tested, you are going to need a shop to run the basic tests, guessing is not really an option. My experience? 35 years as a Ford factory trained master certified technician.

    yes it will still scan the system, i suspect u have a defective BCM, this is the electronic control module that runs many of the systems including the starter lock out for the anti theft system.

1995 chevy try windows wiper radio no work chk all grds and fuses add power to switch on Windows and all 3 work but sparks to much power but not enough on its own


Does the heater motor work? Possible ignition switch causing problem. Turn wipers on and gently move key back/forward slightly with engine running to see if these accessories start working. If they do, ignition switch is at fault

It sounds like you have a grounding issue somewhere. Look up a fuse diagram for the cabin fuse panel. Start from there.

Wiper wiring diagram


Those are accessory functions working off the ignition switch when in accessory position or run position of the key. Were you to check if the wiper and radio fuse had power to them in the run or accessory position as they should, likely they would not. Power from the switch goes to the fuse panel, powering the fuses and circuits that only work with key in on or acc., either a direct wire to the fuse panel or sometimes, fuses get power from an accessory relay that sends power to fuses, but relay has to get a signal from a good working switch before it powers the fuses.
What I'm trying to say, is the bad switch is probably the reason you have no wipers, radio, or mirrors.

Car turns over but won't start fuel injector fuse and ignition fuses are good but no power is getting to them. also the stereo and wipers only work when ignition is on accessory. when its on r


Sounds like it could be a bad ignition switch-the electrical part, not the lock cylinder. When key is in the on position (run), those fuses should be powered. Are all the maxi-fuses good? They distribute power throughout the car's electrical circuits-like the fuse panel, for instance, so check the maxi-fuses. If good, probably the ignition switch is bad.

When I start my 96 ford Taurus I have no radio or windshield wipers or speedometer. But when turn key backwards radio and wipers work


I am betting it is your ignition switch- it is just like any other type of switch, in that it has contacts that eventually wear out. Once you turn the key to start the car, it returns to a position that maintains the contacts to power your accessories, and it sounds like those contacts inside the ignition switch are worn or broken. The "acc" contacts when you turn the key backward are rarely used so they are still in good shape, unlike the "run" contacts which get hit every time you start the car.

When starting my 1997 nissan pathfinder the windshield wipers and radio will not work, but after a few minutes they come on?


There are 2 connecotrs coming off the positive terminal of the battery. They are both big spade connectors and have a tendency to corrode and start creating electrical problems that appear huge. Clean the battery terminals and the 2 spade connectors and that should take care of it. The starting should be better as well as all of the accessories work the way they shoould.
