I have the same issue with my 04, its gotta be a sensor error somewhere in the system. As long as im locked I don't care if the lights blinking or not, but it would be nice to have a CLEAR indication whether the air locker has locked, or if it is in the process of locking.
Does the pump continue to run while it's flashing? If it does, you probably have a small leak somewhere. Mine had the little spring clamp fail inside the diff. I replaced it with a small zip-tie 4 years ago and haven't had any problems since.

There is a plunger sensor that tells the jeep when the locker is locked. My guess is the sensor is bad or the wiring is damaged. If you try to replace that switch you have to remove the differential. There is alot more to it than replacing the switch
I think you can test that switch by crossing the 2 wires & see if the light stops flashing. If not, it is probably a broken wire or bad connection between the switch & the cluster or ground. Make sure the black wire has a good ground.
