Question about 1999 Ford Expedition

1 Answer

99 Expedition accessories stay on after the key is removed. This came to light today when I went to pick it up at the airport. The battery was dead and once I started it, the Theft light started blinking intermittently. I have replaced the accessory relay (#5) on the inside fuse block but the problem persists. Only removing the inside fuse block feed fuse from the power block under the hood turns the accessories off.

Since you have located several components in your wiring you must be using a diagram. Look at your wiring diagram to see if the feed fuse has anything upstream that would cut off the power (like a relay or the ignition switch). If not, then the problem must be that the power from the feed fuse is not being turned off downstream. There must be another relay or the ignition switch is bad and keeping the power on.

If there is nothing listed you have a melted wire or connection which is bridging power to the accessories.

If your vehicle has a trailer plug, check the wires. Something is feeding power to a wire that normally is off.

Sometimes I disconnect the battery and check continuity on the wires. Off is suppose the be Off so that some wires are not suppose to be grounded to complete a circuit. Its a different way of looking at whether some wire is grounding. In simple terms if a pigtail is disconnected and the wiring is showing continuity there is a problem.

SOURCE: accessory outlets do work.

Are you saying that the cargo compartment 12v outlet quit working? If so it has its own fuse.. its on the back side of the fuses you can access with the driver door open. you have to lay down in your floor boards and look up! hard to find, only like 4 fuses there.

SOURCE: When I turn the key on in my 99 Expedition Guages go to maximum

probably when heater core replaced instrument cluster was damaged. check for broken wires or loose connections. on newer vehicles sometimes if you disconnect the instrument cluster you have to reprogram it with a scan tool for the car to recognize it.

SOURCE: Intermittent fuel pump engagement when turning key - 2001 Taurus

try cleaning the connector that goes to the fuel pump, sometimes they corrode on inside. If that does not fix, test the wires feeding fuel pump with a multi meter until the condition shows itself again, if voltage drops to zero or very low then wiring problem, if voltage is unchanged with problem and fuel pump is not working and connectors are all clean, try replacement of fuel pump.

If the alternator is charging the battery, and it goes dead overnight, you have a short to ground in the wiring that is draining the battery.
You can try disconnecting the negative battery cable and see if the battery stays charged when the engine is off.
If it still goes dead, the battery could have a dead cell.

Not the Key but the ignition itself. Replace teh ignition module where the key is inserted to start the vehicle and that should resolve the issue.

My battery went dead on my expedition. When i


I too ran into this problem when battery was removed and re-installed, the radio would power on but no audio. Called Ford dealership and they said they would have to flash the computer at a fee of $95.00 for it to work again. Fortunately my teen aged son who has been at school learning about today's cars said that in most cases removing the negative battery lead for 10 mins and reconnecting will also reset computer. Sure enough it worked and saved me some big coin.

I have a 99 camry the went dead and i tried to jump it the horn blows good the head lights comes on but when i turn the key it says nothing the dash lights doesnt come on its like its not getting any power


There could be several reasons for your problem:
  1. Check your connections for tightness and corrosion. A corroded battery cable/post will diminish the current going to the dead battery.
  2. Check jumper connections
  3. Dead battery; the worse off the battery is, the more time it will take to charge the battery sufficiently enough to start the car; a completely dead battery with bad cells will never recharge sufficiently enough to hold a charge and start the car on a regular basis
Hope this answers your question. Best of luck.

2006 Chevrolet Uplander Parking Lights Stay On


My 2006 Uplander would not shut off the parking lights. I came here for a solution. I saw the answer here, actually the question, and I used the key fob to lock the vehicle. The lights went off. That was a temporary solve. Now, is this a "glitch" or a "feature"?

The reverse lights and heater stay on after the car is off.


It isn't a fuse. A fuse will break the circuit if it is drawing too much power. What you have is circuits that are connected by the ignition switch, that should be disconnected when the key is off. This means that the ignition switch is not operating correctly, and either needs adjustment or replacement.
