No 4WD

[Mark Pearce]

I'm getting a little fed up with my 02 Duramax.
Wheel studs busted.
Rear axle seals replaced.
Injectors went out.
Then the glow plugs.
Now it won't go into 4WD. A little embarassing sitting on the boat ramp this weekend with the tires spinning.
Anyone know of this problem before I go to mt second home at the dealers tomorrow.

If you have the pushbutton transfer case (NP1), you might want to take a look at the switch panel as a possible problem.

Hey MP, did that switch fix yours?

[DmaxMaverick]

A new switch fixed mine when it was only a couple months old. No problem since.

Yup, a new switch did the trick. I was a little surprised when I picked it up at the parts counter. They stocked these switches, and I was told they move quite a few of them....
