Question about Cars & Trucks
I only have power to the font diff in 4wd, in 2wd no power to the rear diff. I can hear the solenoid trying to shift in all button positions but nothing engages except the front diff. I will do the usual check on the solenoid by removing it and cycling it then manually shift to engage the rear diff. I am looking for other, or better advice. its a 2006 660 but new to me. Need good solid advice here please. Randy

your problem sounds like either the transfer case control module located where you hear the clicking sound, or the actuator on the transfer case itself.
try unplugging the transfer case control module and then plug it back in, try engaging 4wd again (make sure your in neutral, coasting at 1-2 mph might help as well) if it still doesn't work check the actuator itself to see if the actuator is trying to engage. if the actuator is trying to engage but doesn't, take the actuator out and check it for wear or damage. if the actuator seems fine and it responds to the buttons when pressed i'd go after the transfer case control module as the culprit. ran into that a few times on those s-10's. 3 out of 4 that i've seen were fixed with a new tccm. 1 of the 4 needed an actuator, check your local junk yard for a working tccm or actuator.
hope this helps!

SOURCE: 4x4 wont engage
There is a switch that has twwo wires going to it, it's located just above the motor on your transfer case,on the drivers side, one plug goes to the motor and the other goes to this switch, it's the motor that shifts it into low and high range, I'm not sure what the switch is called but it tells the front end when to lock and unlock.
Hope it helps

check the solenoid on the front chunk these vehicles have had a lot of problems with these solenoids. have personally replaced about 10 of these on 98-02 models.

If you tracker doesn't require you to be in park or neutral when engaging 4 wheel drive then please try the link above.
