4 wheel high issue

What's up guys!
Had an issue to come up today while driving around in the snow today and need some help.
Whenever I switched over from 2 wheel to 4 wheel high I could tell that it engaged but after a few minutes I was spinning the tries and the front wasn't pulling.
I pulled over and selected 4 wheel low and it seemed to work just fine for about a mile so I pulled to the shoulder and put it back in 2 wheel drive, went down the road a little further and switched it back over to 4 high and nothing.
Few weeks back everything worked perfectly,
Any idea what might have happened?

Think theres a recent thread on this, could be the vacuum sensor thing, vacuum lines, or hub seals/hubs.

Search in this section and I think you'll find it. Most people replaced the part for liek 65 bucks and 10 mins of work on the fan shroud and it fixed it. A few people had bad hubs though. I actually have the same thing on my truck. I just lock the manual hubs and will look into it after winter.

Sorry here ya go, I lied, it was n drivetrain problems;

4x4 not engaging

No, that's not the link shoot. I can't find it, but it's some vacuum switch. TravisH3 knows and will most likely post on here in a few, he had the same issue tried the sensor, nothing, had to replace hub(s). I need to just pony up and buy the part to try it and return it if it isn't it. Need to see if local place carries it to try.

So do you know where I can find this vacuum switch thing on the truck, I just had the truck in the shop so maybe they knocked something off.

Sure, just open hood, left top of fan shroud. Mine is WHITE so I am guessing it's bad. I called the local dealer they said I can't just swap one out for a new one and return it if it's not that, so probably just order it, pick it up, then resell it or soemthing if it isn't htat.

I am guessing mine is original(100% sure it is) and it looks pretty nasty. Actually I need to text a local member and see if I can try his this weekend real fast.

I am pretty sure all the responses are wrong. I am betting your truck, which according to your location is a Texas truck, was pissed at being in snow and that's why it aint workin.

But on a more serious note.....Mine did a similiar thing... only worked when i put the hubs in manual. Ended up being vacuum lines and the sensor.

I know that's right! it's usually just a bunch of ice but this time around we actually got some snow, it was kinda nice!

I checked out the box on the fan shroud like others had mentioned but it appeared to be all hooked up.
Is there a way to test this thing or no?
