Stuck in 4 low

[Scottydoggs]

so i took my mom to a dr appointment, got bored a hr in and decided it would be cool to see if the 4wd still works. good news is it works fine, just wont come out.

so far, i pulled the fuse, beat on the actuator off the t case, took the neg cable off the battery for a bit, nothing.

im guessing i need a new actuator? anyone else had this happen?

Will it come out if you roll slowly forward or reverse while switching the mode?

i tried all that even picked up some speed toss into N and hit the button rolling. nada.

on the bright side i just got it to go back to 2hi. went out and tried to get it to go in t case N hold 2w and 4wh for 10 seconds, red light at the N should light up. it failed to move again, then i hit 2wd and i heard the clunk. and the 2wd light was lit up. it may have been over heated from being over 90 out and idling for over a hr with the ac on full blast. safe to say i wont be hitting them buttons again till i have to lol

also had to reset the ac as it was blowing hot from the battery pulling.

im gonna change that actuator once it gets cooler out. cant have that crap gong on.

I like to exercise the modes in mine about once a month or so.

this would be my first push button 4x4. ive had a number of trucks in the past, they all had the floor shiftier's, never had a issue with them.

now add a small dumb motor and some buttons, and just what you'd expect to happen will one day.

Exactly.probably had my Blazer 15 yrs, and the 4wd failed once--the eyelet in the cable broke--but it broke when I took it out of 4wd. Miss that truck.

You should never run in 4x4 on asphalt - they experience what is called torque bind. 4x4 is supposed to be used on slippery terrain where the wheels can slip and release some of the torque being applied to the gears - on asphalt they cant slip and the gears start to grind into each other binding everything up. And 4- low on asphalt is an absolute T-case destroyer! -never do that.

Could be the push button switch.

ive not touched the 4x4 buttons since it went back into 2 hi. in the end, i think the actuator was heat soaked. ill pay with it again come dec, when im off for the winter lol

The floor shifters were great, but having to get out and pull the hub rings kinda sucked.

i always thought that was the manly part of it all lol.

my 97 and 03 gmc pick ups both had the ifs, that axle spun all the time just like the tahoes do today. but i had a floor shiftier in both.
