    Icon314 I.O.D fuse keeps blowing

    Anyone experience this problem. The I.O.D fuse keeps blowing. What is the I.O.D anyway. When it blows I have no interior lights, no radio, no power locks and no power windows. This is for a 1993 XJ. Check all the rest of the fuses under dash and under hood. This one is the culprit....The search function when it is working doesn't have a match for I.O.D. Anyone have a fix for this............thanxs

    I did a search for 'IOD' and apparently it stands for Ignition Off Draw. It powers your stuff that comes on when the key isn't in the ignition (dome lights, etc). One guy mentioned something about a short in his side mirrors causing it...

    Anyone else have anything. I must have a short somewhere. Right now it's too cold and way too much snow on the ground.

    I had the same problem. On my Jeep, I use the security system to lock/unlock the doors all the time. Once, the fuse blew and I couldn't unlock the doors. Had to drill the locks. Long story, don't ask.

    Anyway, I traced the short to the driver's door switch cluster. More specifically, the power window lock/unlock switch. If you haven't pulled the switches out yet, you'll find that all the electrical connections terminate in a big see-through plastic block that all the switches clip on to. It's a really cheap design and I will soon replace all the switches with momentary toggles.

    Just another example of the fine engineering that went into our Jeeps.

    Having the same issue on my 97 XJ.

    I checked the driver side door switch and it seems they changed the door switch cluster to control modules after '96. Traced the problem to what seems to be the door jamb switches. When they are connected and out in the door open position, the IOD fuse blows.

    Basically if the door jamb switches are pushed in, the fuse does not blow and everything works properly. However, when the ignition is turned on and the door jamb switches are still pushed in, the door locks fail to lock while the unlock side of the switch still works. At any time, allowing the door jamb switches to spring open blows the fuse and everything on the common circuits fail.

    Thanks for any help.

    Normal.

    If you open the door with the key in the ignition switch a chime will sound and the doors will not lock. Keeps you from locking your keys in the car.

    With the key removed the truck thinks (lol) that you have your keys in hand so it's okay to lock the door.

    Nice feature.

    Default IOD Fuse 99 Cherokee kept blowing

    I had the same problem, real intermittent. Ended up being a short/grounding in the wires leading to the overhead dome light. Passenger side near where the sun visor mounts there's a sharp edge that eventually cut though the wire casing. Hopefully this will be some help to someone, sure took me a while to track this one down.
