4x4 issues
Can't get the truck into 4x4... Have checked the vacuum lines an they are good. Also the air and heat work just fine. Hubs are seized in auto. The dash lights on the shift in the fly **** do not light up. Have checked all fuses. Any ideas would be much appreciated. Thanks

When you shift the **** into 4x4, with the truck in park can you rotate the front drive shaft by hand? This will tell you whether the transfer is actually getting into 4x4, that is if you cannot rotate it the transfer is shifting into 4x4.
To see if your hubs are truly locking up, jack up the front wheels and spin the tire, look and see if the small u-joint inside the steering knuckle is rotating. If not, try it by manually locking the fronts and see.
Please let us know the results and we can take it from there.

Right now there is several inches of snow on the ground so will jack truck up tomorrow. As for the driveshaft, it does not spin in 2 high or 4 high. Right now the stock hubs are on the truck and are seized in auto. Have tried everything to move them but they don't budge. I do have a set of warn premium manual hubs to put on as soon as the weather gets better.

Been PM'ing with another member also and he was able to move a seized hub selector **** by using a large set of channel locks. Maybe I didn't interpret you correctly. If you're talking about "seized in auto" meaning the "selector **** is seized in auto" might try dousing it in teflon-based lube in the annular space between the selector and hub body and applying a little more oomph to it with some leverage.
That light on the dash failing to illuminate is pointing to a fuse or relay, though. Are you referring to lights on the **** or the light on the instrument panel indicating 4x4 is engaged? The **** lights are just illumination for night, they're meaningless for actual operation unless the switch got unplugged from behind.
Any heartbeat at all in low range?

I have actually used channel locks and ended up breaking part of the plastic in the hubs. Will try again. The **** lights are the ones that don't come on at all. The dash light does illuminate when starting the truck. But does not come on when I move the switch. Also I don't know if this makes a difference or not but I am running the edge attitude cs so so far none of my dash lights have come on while driving I.e. the engine light, air filter light, 4x4 light

I'm not very knowledgeable on tuners and chips, but there's lots of folks here that are. I can't imagine the tuner would tune out 4x4 though.
When you said the fuses were all good, you checked the ones under the hood, too, right? And the relays located there, too? Just making sure you didn't mean just the bank under the dash.

I did not because the only 4x4 related fuses and relays I saw were located in the cab. Will do that today after work. Also about the **** on the dash, the annoying reverse beep button works and lights up fine, probably not on the same fuse though now that I think about it. I read a post on here a couple days ago about a plug that goes to the transfer case that comes unhooked here and there. I looked at my harness and it's dirty but hooked up, also not sure exactly which plug was being referred to and of course can't find that thread again.

I don't think the tuner is not allowing it into 4x4, I think it stops all dash lights from turning on. As in my alternator went out the other day and not once did the battery light come on, on the dash. I noticed from the volt reading on the tuner

That plug is the one that supplies the shift motor for the transfer case. That being unplugged would certainly be filed under "unhelpful." But, as you said, you checked it.
Definitely check everything under the hood, too. The ESOF shifting relay is under there on mine. Positions 17, 40, and 41 in the power distribution box all pertain to the ESOF system on mine.

Just checking the front drive line does not help much. If the transfer case is shifting but the hubs are not, it will not spin. If the hubs are locking but the transfer case is not, it will not spin. You need to jack it up (use jackstands) to see what part is failing to engage.

Well don't know if this is just me being dumb or not but I can't for the life of me find a fuse box under the hood. I found 5 or 6 relays in a cpl different boxes but no fuses, I have searched and searched and finally found something eluding to in 2002 they moved the box to under the steering wheel. But it also said it was late 02 and mine is a January 02. So I got nothing, guess I'm just going to put the warn hubs on tomorrow and go from there

Far right next to the brake reservoir as you're looking at the engine with the hood open (driver's side), black plastic box right up against the fender.
Mine's an 01, I don't know if the 02's did away with the underhood box. That seems like a pretty big electrical change, though.

Try switching a couple of the relays from one to another under the hood . My relay's box had been taken out by the previous owner which had me scratching my head for awhile checking the **** on the dash , plus the motor on the transfer case and then finding the relays under the hood and checking them . I finally got it working properly by switching relays because one had gone bad . I guess the previous owner had trouble with the 4x4 and did some monkeying around with the relays which had gotten some corosion in them and shorted one out . If the relays are working properly , you should be able to hear the transfer case motor engage ( engine not running but key on ) .
