Just to be clear, did you press down on the bottom of the axle lock switch?

 

[BigDan]

yesssss , tried multiple times too .....

Just asking Not everyone realizes it's a rocker at first.

I wonder if it's the sensor and the locker actually engaged? Seems odd that BOTH would be bad... Fuse? Sorry, haven't seen this happen.

all fuses ok ...as ^per the owner manual ( M33 fuse )
they definitely dint lock ,,,,,cause I turn real tight no tire chirping noises
I have a 86 CJ , with lockers , believe me woulndt turn smooth with lockers on

The manual for my daughters '12 (just happened to have the PDF handy) states M3 is for the lockers, M33 is for the Powertrain Controller. It just seems very odd for neither to blink, so the common thing could still be the fuse (unless you made a typo).

The relays next to the battery by the fender, take the purple wire and run a jumper to ground, if the fuse is ok that should engage one of the lockers, the light will blink on the dash.
