ok need some help still kinda new to the 4x4 community my 90 Toyota 4runner, question is my 4x4 hasn't worked since i got it and im not sure what is wrong i have been trying to figure this out, here what i have i get no light on the dash but i get the qear reduction from my transfer case so i have been looking and i was wondering if the transfer case switch could cause this i have read that the switch is what tells the solenoids to engage the front diff but like i said i am new to this so any help will be appreciated
