Hello, new to me 2014 JKRU, 2in lift, 35 tires. Went on first trail yesterday, signal peak loop starting at eagle lakes ending at Cisco Grove. Made it up and down just fine.

Halfway up the rear diff light started blinking and blinked the entire time rear diff was locked. Did some test runs today. Front and rear lockers locking and unlocking fine. Front light stays on solid but rear light blinks still. When I unlock rear diff the light turns off.

Did a lot of searches and the results are for diffs that are stuck locked or won't engage or the light blinks continuously even when not engaged. Any help greatly appreciated.

 

Sound like the plunger on the rear diff that closes the circuit for the indicator isn't working. Your locker has two connectors on it. One actually tells the locker to lock. The other is a plunger that grounds a circuit when the locker is locked and opens a circuit when it's unlocked. This is what tells the jeep the status of the locker.


Post #8 of this thread show's the picture of the plugs and what each one does.
