So, it's been a few months since I've used the locker and today I thought I'd give it a litte test and it failed! <img src="/forums/images/graemlins/frown.gif" alt="" /> I have ice on 1/2 of my driveway - so i parked with one side on the ice and others on concrete - and I was just spinning the 1 rear tire. So, I flipped the locker switch (not factory - it's retrofitted e-locker so I can and have engaged it in 2wd) and nothing - still just spun the 1 rear tire. I backed up drove forward in a little "s" to try to get it to lock but nada - just spun the 1 rear tire. I even went out to a dirt field were I've tested the locker before and it isn't engaging. As stated, it's a retrofit - so I don't have a little light on the dash to tell me it's locked on not.

I'm pretty sure it's not the wiring cause when I flip the switch on and off I can hear a click behind the dash and little 2 second humming at the differential. Even so, still doesn't lock up.

Any ideas what else might be going wrong? or what I can check.

Thanks,
John

is it possible there could be some moisture getting into the assembly and freezing something up? not sure exactly how the lockers work etc. seems like the heat generated by the diff would heat it up though, just a thought.
