2005 Suburban Stuck in Four Wheel Drive ?

[Earl Cordova]

We have had a 3/4 ton 2005 Suburban four wheel drive with an automatic trans for 9 years.

It has buttons to the left of the steering wheel where you can select 2 wheel drive,

4 wheel drive high and 4 wheel drive low.

While we mostly drive it in  2 wheel drive, the other two 4 wheel drive options get used about every weekend.

Last weekend it was switched to 4 wheel drive high and now no matter what I do, it stays there.

 

Any ideas where I should start looking ?

Your selector switch, the wiring /plugs that it operates through could be bad but I'm betting the "motor" (Chevy doesn't call it a motor, they call it something stupid) go here: https://www.partsgeek.com/catalog/2005/chevrolet/suburban_1500/transmission/transfer_case_motor.html

It was the transfer case actuator (motor).

Maybe you should ditch work and go to the casino ?
