    Bypassing the “key on” circuit for accessories

    I’m turning my Expy into a camper/shell (removing ignition, battery, engine, etc.). Since I’ll be using my 12V power supply to power my radio, sunroof, windows, door locks, etc., how do I best tweak (e.g. jumper, splice, etc.) the circuitry/relay box(es) to “think” my key is “on” all the time...

    Help with diagnosing wire

    Can anyone tell me what this wire is? I was changing the ignition switch and when I took the bottom cover on the steering wheel column off this wire was just hanging? Just has a little male prong coming off it. I can’t find where it plugs into? Any help would be greatly appreciated!

It is a pretty cold morning here in Indiana, with a wind chill below zero. I am sure this has something to do with it. The wheel moved...

    2020 Expedition occasionally doesn't start

    Hi, just bought a 2020 XLT. Occasionally (and generally when in a hurry), the car won't start. Press the ignition button and lights flash, headlights flash, but nothing turns over. 15-30 min later, starts right up. Happens once a week, maybe less. Saw some threads on internet that this has...

    Techs? Possible link between A/C and ignition coils??

    I had a P0351 code last week and the AC stopped working on the same short trip. P0351 is something wrong with the ignition on cyl #1, tested power and coil, the coil had continuity no resistance. But When I replaced the coil (I did nothing else at all) the AC started to work again Is this a...

    No electric after battery replacement

    This is a friend's vehicle. Its a 2004 Navigator. It had to be jumped due to no start. She took it to Advance Auto Parts to test the battery. The battery was bad, so she bought a new one and replaced it herself. Afterwards, there is no power to anything with the key turned to any position. The...

    When we try to start our 2012 Expedition the ignition Switch fuses pops every time. I replaced the Ignition switch, and that didn't help. Should my next thing to look at be the Starter?
