Hi All, I have a 2002 3.7 liter V6 Tacoma, SR5 ext. cab with a TRD off-road package. My 4wd does not work--when I push the 4wd button nothing happens, when I shift the vehicle into 4 low, my truck lurches forward and feels like it is engaged, but all that happens is that the truck goes into a low gear and the front wheels do not turn. This will throw all of you for a loop as well--I do not even have a 4wd indicator light on my stock dashboard, nor have I ever messed with the dashboard. I bought the truck in 06, and have never tampered with the 4wd or used it, though I have tried to engage it plenty of times...I live in South Carolina and do not go off-road. Any clues as to what might be the issue?
