Toyota E-locker Issue ('04 Taco TRD O/R)

Ok.. got an issue that happened a couple weeks back. Basically, the e-locker on my truck is permanently engaged. If I push the button, the RR Diff light just flashes, never goes solid and the locker never disengages when the button is turned off.

I remember reading somewhere there is a sensor/switch in the locker motor that can go bad, which controls the engagement. Was wondering how difficult it is to fix/replace it and if replace what the part # is and an idea on what it's going to cost me.

I don't particularly mind it being locked all the time, except it chews up a set of mudterrains nicely lol.

 

Dont remember the part number but its 10 minute job. Its next to locker actuator, look for locker harness spliting into two plugs. one is 6 wire plug other is 2 wire plug. 2 Wire plug goes to switch. Dont mistake it with breather tube.
