electronic disconnect not working

Last winter i noticed my electronic disconnect (stock Rubicon) wasn't working when the temperature was below freezing. But it worked on warm days.

Now I've been gone most of the summer and haven't engaged the disco since spring. Just tried it today and it's not working at all. (yes I'm in 4lo) when i engage it, i hear a noise but it doesn't do anything. The light keeps flashing and the sway bar is connected.

Anybody knows what might be the problem? The while system is 1700$.from mopar, so suffice it to say that i wasn't to fix the one i got.

Have you tried rocking the Jeep side to side to see if it's torque locked? Are you in motion while trying to disconnect? BTW, contrary to popular belief, the swaybar will disconnect in 4hi as well as 4lo. In 4hi, you just need to keep your speed below 18 mph or it will try to reconnect. That makes the light flash. From the owners manual on my '11 JKUR...

NOTE: The stabilizer/sway bar may be torque locked
due to left and right suspension height differences. This
condition is due to driving surface differences or vehicle
loading. In order for the stabilizer/sway bar to
disconnect/reconnect, the right and left halves of the bar
must be aligned. This alignment may require that the
vehicle be driven onto level ground or rocked from side
to side.

Well I didn't try rocking it but I tried it on flat a very surface. When that didn't work, I drove around a little on uneven terrain to get the left wheel up a bit then the right one just in case that could "unstick" it... nothing doing.

What worries me is that I hear it "working" when I press the button. I can hear a little noise as if the disco motor is turning or whatever but it doesn't disconnect the sway bar. Has no one had that problem?

I came across this thread awhile back, I'd unbolt the motor and see what's going on.

These are pics of a bypass, but it should help you see where the problem is.

Thanks for that link. So apparently that's a common problem then huh? Doesn't look good for a quick repair, but I'll open her up before it gets too cold.

Unbolt the motor and see if the motor is doing it's job or if the cam portion is working. (whatever drives the receiver portion in the pic). It'll probably take a helper. Then see if the sway bar side's pin is stuck. I don't know that it's a common problem, but I'll bet you can figure out where to start.

You can google for a better blow up diagram of the internals.

I'd get it fixed (hey it's a rubi), but like you I wouldn't spend 1500 on a new unit. I take it apart until I found what is broken.

The edisco unit isn't sealed properly from the factory, so crap gets inside of it and starts to mess things up. After a while it will mess it up to the point of non function. You will hear the motor trying to work, but nothing happens. What you need to do is remove it, take it apart, clean it, grease it very well, and seal it with RTV (like the diff covers). Chrysler is aware of the bad sealing issue, but as usual, choose to do nothing about it.
