    Did you put your truck in 4lo? It has to be in 4lo to use the locker unless you did the grey wire mod.

    As a starting point, you might check the factory service manual (sticky in the 1st-gen forum) for the Rear Diff.

    Usually you gotta roll forward (idle in drive) and you can hear it engage. When I first got my truck it took a LONG time for it to engage. Now that its been used (a lot) it engages a lot quicker

    Do it on dirt. It took me a good 30 or so feet until my locker engaged the first time I used it. Never try it on pavement.

    Does the Rear Diff light come on and blink on the dash when you push the button?

    The RR Diff is supposed to blink in the dash by the speedo and stuff until it works then it just stays lit up. Like TRD4x4858 said check the fuses 1st. Hopefully its something as simple as that and not a major problem.
