2006 toyota tacoma 4wheel drive malfunction

i am very new here , but i have been working on this tacoma for a long time , i have replace the front actuator twice lately thinking that i had gotten a bad one, still does the same thing , i have checked every thing that has been mentioned on here , i am now getten power to the 4x4 side of actuator when the selector in dash is engaged , front end locks in, all 4 tires pulling , but when turn back to 2wheel drive there is only a blink of power at the actuator , not enought to lock out of gear, any one know how i can check for this problem,also i have unplugged the front actuator and the trnsfer works perfectly in and out with out turning key off, please anyhelp would b appreciated

 

OP, I see that no one has yet replied so let me give it a shot.
Do you have an VOM meter and a little experience with the thing? And can you easily locate the major parts involved, you obviously have found the ADD actuator? If so I can send you some diagnostics. You may have to PM me to get my attention as I do not frequent the forum much.

 

I am going to state the obvious hear so, make sure the truck is in motion when your going from 2h to 4h and 4h to 2h

 

ok, windigo ,my truck is on jacks in the air, i have tried it in gear wheels turning and stopping going to reverse , neutral , by just spinning by hand , truck goes in gear but the front diff not coming out , test light at the plug shows only a brief blink when u try to shift out , i am at an all with out diagram, thanks for ur help, dont give up on me,

 

You'll get it
Sorry I can't help.more I just dont know the system.
