front axle lock wont stop blinking

Hello everyone, i have a new to me 2004 rubicon and am experiencing some problems. I posted earlier about the axle lock switch not working at all and dash lights (front and rear axle, 4wd) not lighting up. 4wd works fine, but i do not hear the lockers engaging. anyways, now the front axle lock dash light is blinking at al times and won't go off. I didn't even push the button, yet it continues to blink. How should i go about fixing this? thanks in advance

Try unplugging the electrical connector at the differential and see if it stops, if it does then the sensor inside is bad.
When its blinking, is the pump running or not?

Before the wire goes into the differential there is a plastic connection, not near mine right now, but involves a small safety clip that come backs out then you have to sweeze the connecto then pull apart.
If your pump is not running, and you have been driving it around, then we can assume that the locker is not locked.
There is also another sensor on the transfer case that may be bad or the main switch. The dash switch doesn't look like much, but there is a lot going on inside the switch and know to go bad. Hopefully it is not the sensor in the differential because that is a pain to get to, big pain... Sounding more like one of the last two I mentioned which is way easier to swap out.
Do a search here,rubicon locker, there is pretty good proceedure on trouble shooting those things.

I forgot to mention, DO NOT unscrew and remove the actual differntial sensor, Jeep made it so that you have to pull out the axles, and take apart the differential to re-install the sensor,...yea stupid set up...

My light was doing the same thing. When I went to ARBs I checked the switch and it worked fine. I suspect the problem was the gadget that operates the lock is trashed and allows the ring that operates the switch to float, allowing intermittant light.
