Question about Ford F-150

1 Answer

Security System I have a 2004 Ford F-150. I was removing some of the dash panels looking for something and the entire cab suddenly lost power. I tried starting the truck and the starter just clicks and the security light blicks everytime the stater does. I reinstalled all the dash panels, disconnected the battery then reconnected it and tried it again and the same thing happens.

You appear to have blown some fuses, you never play with electronics like the dash with power connected, you can short things out, blow things up. disconnect your battery first, remove the panels you removed earlier and check carefully for burnt wires damaged plugs etc then reassemble checking all fuses as you go, don't forget to check all earth points. after it is back together reconnect the battery taking care that connections are good and the battery is charged, now that i have scared you, the problem was probably only a bad connection on the battery but you can damage the BCM doing what you did, that may lead into repair in excess of $1000

SOURCE: 1998 Ford F-150 won't start w/ the key, but will w/ remote start.

Make sure the key is good. If you have two keys try the other one and see if it starts. For some reason the computer is not reading the chip in the key. The keys might need to be reprogrammed.

SOURCE: security light flash no security system on truck

sometimes turning the ignition on 3 times quickly without starting will reset the computer. If the van has power locks and keyless entry then try using only the keyless entry. Sometimes your car wont have a alarm but an anti theft device which will not allow it to start if it goes off or something triggers it.

Check to see if you have a computer chip on your key. Chances are that the computer chip or the reader in the ignition keyhole is not reading it properly. If you leave the key on, engine off, for 15-20min. that security will reset and the light will go off. Turn key off and now try to start engine.

SOURCE: my 79 ford 9000 dump truck has no power after the

There is a solenoid mounted in the engine compartment, usually on the driver or passengers side on the inside of the fender that allows full battery current to reach the starter. Assuming the starter is good, you can test this terminal with a test light, there should be four connections on it. One is just a ground, some of them dont even have a ground, the unit is self grounded. The other small terminal on it is power from the accessory, or key (ignition) switch. Use a test light to check for power at this terminal. You should have no power when the key is off, and you should have full power (12 volts) when the key is turned all the way to start (as if you were cranking the vehicle). If this tests okay, try jumping across the other two terminals (they are both bigger than the first i described). One comes from the positive side of the battery, the other leads to the starter. Turn the key to the "on" position, and use a piece of heavy gauge wire to "jump" across the terminals. Caution: this is a bit hazardous, use good judgment, and be aware that leaving a wire on there could cause the wire to burn, or something to catch fire. All you want to do is tap the wire across, and see if the starter attempts to turn. Most likely, it will. You'll need to disconnect the batteries, and buy and install another solenoid. Just be sure the new one is connected as the old one is. Any other issues, please feel free to contact me back.

Thanks for asking!

The dash lights on my 2006 F150 do not work when the head light switch is in the "automatic" mode. The tail lights do not work when the same switch is in the "headlamp on" position, but...

I would check the grounds for the BODY SECURITY MODULE. I think it is near the back of the cab, behind the driver. There is one ground on the cab panel and the other is on the driver A pillar, probably below dash, behind kick panel. The BSM interfaces witht he Autolamp.

black/light green wire on cab panel and black on A pillar.

The defrost suddenly quit working this morning and the cab smelled funny in the ford F150 XLT Triton truck I am driving.

Look under dash panel on drivers side above gas pedal is a servo motor that turns a large roundish cam plate. With the key on, see if the cam turns in proportion to the heater control. I have seen some f-150s where the foam that seals the function doors in the heater box falls off and jams the doors up. If the cam plate only turns a little, remove the servo and cam plate(8mm screws) and see if all the levers under the cam move freely. if they don't then you probably have a jammed door and the dash and heater box need to be removed to fix it. BIG JOB!
Hope this helps

Ford f-150 brake light and blinker problems (from towing)

Check the fuse box located in the cab down by the drivers left knee. check all the fuses there, also consult your manual and check the fuse for the brake/tail lights. This sounds like a fuse problem more than anything. Thanks for using fixya! Good luck!
