Thread: Stuck in high

  1. #1

    Default Stuck in high

    I've searched...I've come up empty.

    1996 GMC Suburban 1/2 ton 4x4 350

    I switched from 2 to 4 hi and 4 hi just blinks. I can hear the actuator (?) click but that's it.
    Just blinks. Pretty sure 4x4 is not engaging. 2 Is fine. 4 lo wont engage either.
    Luckily and hopefully we are nearing the end of the winter weather but I'm sure there will be at least one more good one..

    So I'm wondering were the best place to start is?
    From what I have read its not uncommon, just trying to narrow things down. Any help would be great.

    Take a close look at the front actuator, since that is the most common fault, and go from there.

    If I can hear the actuator "clicking" how do I tell if its the culprit? Couldnt it also be the actuator motor?
    How would I tell the difference?

    You can pull the actuator out and then have someone turn the switch and see if it moves.

    O.k now we're getting somewhere. So If it moves that would mean the motor is good, actuator is bad?

    The actuator and motor are all in one.
