Hi, I have a 06 tacoma 4x4 reg cab, 4cyl, manual trans, and the 4x4 selector is the turn switch type. It will shift into 4hi and the light comes on, but when I switch it into 4low it does not shift into it and the 4low light does not come on (it stays in 4hi). No beeping either. I did as the manual said: come to a stop, put in neutral, depress clutch all the way down, push and slowly switch into 4low from 4hi. I've tried turning the wheel both ways, and moving forward and backward multiple times. I don't see why the 4low light won't come on or even blink. Nothing is showing up on the code reader, and I've checked the fuses and conections on the t-case actuator. I hope it's not the actuator (i've heard they're around $800). I would appreciate any insight.
