I need a little more information from you to properly tell you what you need to do to fix it. First I need the year of the truck. the make ford,chevy. ect. and the model f150 ect. ect. also what size engine. also will the truck even start now because an AC fuse has nothing to do with either the primary or the secondary ignition system. also explain in detail as much as possible to me. I will have your truck up and running. Sincerely, COCC TECH.

Normally fuse that had gone out or has melted, is caused by overload in the circuit. This may have been caused by a short. Check out the wiring if there are some that may have gone bad that includes the ground cables. Check out the wiring underneath the dash as the issue with the electrical affected the wiring for the ignition. If those checks out OK, check the wiring harness to the ECU if they are intact. I am unsure with the F150 but there are some cars with fuses found under the dash. You may want to take time in checking if there is one while looking at the wiring.

In the fuse box, please check if there's is missing connection or another melted fuse. Make sure the electronic control module is properly seated without any grounds.

2005 merc grand marquis Headlights keep blowing a fuse


Does your Grand Marquis have head lamps with auto lamps ? Which fuse keeps blowing ? Could be a shorted LCM - lighting control module ?

Lighting Control Module (LCM)
The LCM eliminates the electronic interference and heat associated with the thermoelectric devices used previously. The LCM is a microprocessor-based module that controls several vehicle subsystems. It responds to electrical input signals from various switches, sensors, and external modules..

2006 Buick Rendezvous 10 Amp ABS fuse keeps blowing. What could be the problem?


There is a shot to ground in the ABS system ! If familiar with electrical trouble shoot , find a wiring diagram an test the B+ power circuit ! That fuse supply's power to the electronic brake control module , if no short on wire from fuse box to brake control module , the module has an internal problem .

1994 lincoln continental randomly dies while driving. It's getting fuel. What else could it be?


Thankfully, mine has never done that....if by 'body control module' you're referring to the electronic 'black box' that monitors various inputs and controls timing/ignition to make the car run; then it seems like you've already covered most of the obvious things that could be at fault, here. If by 'dies'; you mean the car actually stalls out while you're going down the road? Does it immediately restart after it happens, or does it have to sit for awhile, before it will fire up again? Do you lose your digital display (+ radio, fan, etc.) when this happens--or does everything turn off, then it all comes back on--except for the engine? Since it never happens when idling, it could be some kind of intermittent electrical problem--(ground strap coming loose?) caused by the vibration/bounces of driving....I'd look there first.

Which means the A/c fuse went first. Isolate the A/c line and see if by patching any of the fuses restores the engine ignition. Don't bother for lights and other accessories, get the electricals changed a.s.a.p...........sodeep

Whiledriving the revs drop, and there is no drive, then stalls


Well it's possible that when the mechanic sprayed your engine he may have also used cold water or lukewarm water to rinse it. Or the silicone itself was cold coming from the can. If the coil/coil packs were hot at the time, or the ignition module was, it is likely that the cold liquid(s) spraying on the hot electronics may have cracked either the coil magnet or the ignition module causing them to fail. Repeated misfiring from damaged coils or ignition modules can cause failure at the rotor and distributor cap by constant crossfiring inside. You'll want to remove the distributor cap and look inside for evidence of burnt, broken, or cracked electrodes. If they appear blackened or melted/burnt you will definitely need to replace the cap and rotor. Before replacing them however, you may want to take a close look at your coil or coil packs and the ignition module. One way to check the coil to see if it is cracked is this: Place the vehicle in a darkened area or wait til it is dark out if you can't move it. Since the vehicle isn't running everything should be cold so this test won't damage anything any further. Fill a spray bottle with warm water. Spray a mist of water on the coil. Have an assistant crank the engine and watch in the dark the area of the coil. If you see a lot of arcing or a halo like effect of electricity you will know the coil magnet is likely damaged. If not, it is probably ok but you'll want to have the ignition control module tested. You can probably have this done at a reputable parts dealer or garage who have the correct electronic test devices. If both the coil and the ignition control module check out ok, go ahead and replace your cap and rotor then try starting her up. Anything that tests bad obviously must be replaced first to get it running and to prevent further damage to the ignition system. If you are getting no spark it is most likely the coil, second most likely the ignition control module. Good luck and let me know how it goes.
