    Default my blazer wont go into 4x4 low

    ok so if i push 4 hi the lights flashed and i can hear the hubs lock out but when i put it in neutral and push 4 low it flashed for about 30 seconds and goes back to 4 hi. one time i pushed 4 low and all the lights on the 4x4 buttons went off and i put it in gear and u could tell it was in 4low because of the rpms it went about 10 feet and slammed into 2 hi very very abruptly. any ideas on what maybe wrong?

    My 1998 Jimmy is doing the same thing. The mechanic at the Chevrolet dealership where I work says it is the encoder motor.

    Definitely sounds like an encoding motor or 4wd module problem. Do you roll the truck slowly when going in and out of Lo Range? I find that helps alot.

    i tried but it wouldnt work either. i got stuck the other day and read the owners manual and it says to put it in neutral push 4 low and put it in park to force it to go into 4low. i tried it and it worked but i had to disconect the battery to get it to go back into 2hi. we jacked up the truck and u can hear the hubs lock when u hit 4hi but the wheels didnt turn???? does that mean its something worse

    are you rolling at 3-5 mph when you try to go into 4 low? thats the way every 4wd truck i have been in does it, get rolling, put in neutral, and hit 4 low, then it should go
