Its an easy diagnose. In most cases its the electric/vacuum solonoids on the firewall that controll the 2wd/4wd shifting. Have the truck running with someone pushing the 4wd button, under the passenger side tcase there are 2 vaccum lines running to the diaphram. There should be vacuum going to one side of the dia. in both positions on the switch.

But the front diff is working when you push the H4 dash button . ?

So its been awhile since I posted this, and my only excuse is that there is no wheeling in Sitka, and I didn't need the 4x4 much last winter. BUT: I got underneath my rig this am and had a buddy sit in the driver seat. We had it running in N and in 4wd. He would switch it into low, and then into D and I couldn't see/hear/ feel anything in the solenoid. We did the same thing with the button out and nothing.
Should I replace the vacume thingys on the firewall first?

If its engaging 4wd then there is nothing wrong with the solenoids, they only control the engagement of the front output. When you say it wont go into 4wd low, do you mean it wont shift or that when you shift it it does nothing? Sounds like a linkage problem to me.
Actually the vacuum actuator switches between 2WD High and 4WD high.
The manual shift lever shifts between 4WD High and 4WD low.
BTW, even if the vacuum actuator isn’t working, you can still manually shift to $WD low with the shift lever.

Nope, that little tidbit got me stuck many moons ago. The shifter only switches between high range and low range. There is a switch on the shifter mechanism that will engage the 4wd solenoid when shifted into low range, but front output engagement still hinges totally on the operation on the solenoids on the firewall.
When you push the 4wd button, does the light come on? Can you turn the front driveshaft with the hubs unlocked and the 4wd button engaged? I know you said that the front wheels spin but i think you may find that it is not going into 4wd at all. You should be able to shift it into 4wd or out of it by switching the vacuum hoses that run down to the hardlines on the solenoids.

It goes into 4low. The front tires spin... I used it last winter to get outta my driveway, and then just switched into 2wd once I got on the road. I don't remember if the light comes on, I think maybe it doesn't? I just don't have 4high.
Well the only other thing i can think of is that the switch is no longer working and the only way to engage the 4wd solenoid circuit is to shift it into low. That is basically the only way that 4wd would work but only in 4low. Basically, if it is shifting into 4wd at all then the solenoids are functioning. Like i said, engagement of the front output and low range are two entirely different systems. You really need to shift into 4low and see if the driveshaft will spin with the hubs unlocked. Ill put good money that it will.
As agent orange said, if you can shift into 4WD at all, the the vacuum actuator and solenoids are working. Check the transfer control relay (under the dash to the right of the steering column), the dash-mounted pushbutton switch and the associated wires and connectors.
I would have to respectfully disagree.
Mine goes into 4WD low with only the lever. I don't have to press the button on the dash for low range.
Unless I'm missing something (me, not the Cruiser!)!!! The shift lever is directly connected to the T-Case and moves the fork to engage the front gears. There is no vacuum associated with the shift lever.
I'll have to go put mine up on jack stands and try it!
Edit add: I was just mulling this over in my feeble mind. I just (3 weeks ago) put my tranny and T-Case back in and while I was tightening the nut on the back of the tranny output shaft (input of the t-case) I shifted it into 4-Lo to gain as much resistance on the nut as possible. When I did, the front flange turned. This was with the t-case out of the vehicle so the solenoids were not even present.

The 4wd shifter has no direct connection to the front output. If your solenoids arent working, you cant put a 62 into 4wd, period. Believe me, ive tried several times, and unfortunately thats not how it works. I really dont know what is up with your case that it made you think it was working that way, maybe coincidence?
4wd is engaged when you pull the shifter into low range because that does the same thing as pushing the button, there is a switch on the tcase that does the same thing as the dash button. If you disconnect the tcase switch, its like having a push button twin stick setup, which is pretty handy.

the shifter only shifts from 2HI to 2LOW...
The button runs to a vac operated shifter that shifts a completely different part of the case. With out hitting that button there is no way to shift into or out of 4wd unless you crawl under the vehicle detach the hose and suck on it.
If you guys had your hubs locked and saw the front drive shaft spinning it might have confused you into thinking you were in 4wd when in fact you were not....

Agree: the shifter shifts between high and low range AND, as agent orange said, activates a switch which does the same thing as pushing the button on the dash. If this switch is disconnected, then the ONLY way to shift between 2WD and 4WD is to use the dash button.
As agent orange pointed out, disconnecting the switch gives you independent control over 2WD/4WD and High/Low so that you can run 2WD low.
