I took my blazer for a four wheel drive and since then I haven't been able to shift into park. I didn't drive hard while in 4 wheel. I can manually shift it to park, the transmission will engage in all gears manually under the vehicle . I have also adjusted the linkage both toward the engine and to the rear of the vehicle to no success
Is it possible the lever for linkage got whacked and is bent?
SOURCE: 4 wheel drive not working
Vacume lines or vacume switch on transfer case,or vacume pod to front axle.

when you engage it in 4 wheel make sure you are getting vacuum to the acuator just pull the hose off and feel to see if there is vacuum if not check all vacuum hoses
SOURCE: I have a 1986 Chevy S-10 Blazer with an Automatic
Clarification please... Do you mean by "go into" as the shift linkage will not move into the forward ranges or that the vehicle will not move forward? Both are possible scenarios but very different. Let me hear clarification for sending a test procedure for either one.
SOURCE: transmission leaks, clunks into gear
Well your clunking noise is most likely the u-joints the leaking pan is the tranny pan what you would have to do is get a tranny kit and change the pan gasket tranny filter and fluid or take to a shop and have a tranny service done.
Testimonial: "thanks a lot, man. i will def do what you suggested. Im gonna try and fix it on my own. hopefully i dont mess it up and it works. ha ha. thanks again!"

Check the fuse to the 4x4, if the fuse is good then check the 4x4 electric motor actuator on the transfer case. You should hear it work from 2wd, 4hi to 4low and back to 2wd with the push of the switch. if you don't hear it working then check the wire harness at the actuator motor, look for any damages like corrosion or cracked wire connector clips. If the 4x4 actuator is working on the transfer case, then the front hub 4x4 actuator may have gone bad and that's located on the front differential. It's common for the clip there to corrode and break and is an easy fix with a new collar pin, at worst it's the diaphragm on the vacuum actuator that is located under the battery tray. There is a vacuum switch on the top of the transfer case, driver side but when that fails, your front hub stay's locked in the on position. Good luck and keep me posted and hope it's a simple fuse that has gone bad. You can pick up all these parts at Auto Zone or Parts Source and they will have the step by step instructions for you to get the job done with common tools.
