OK I have a buddy with a 200? double cab tacoma. Typical TRD, 3.4/auto with electric rear locker. His locker won't engage and it goes blinky-blinky on the light or switch when he tries to engage it. He wants me to help him fix it. Of course being me I think he should weld it up and throw the switch away but that's not his goal.
Where should I start?
