1997 Ford f150 xlt : 4x4 is engaged no matter what. I disconnected the battery multiple times only to have it go back to 4h from 2wd, the actuators are also disconnected I think the connector going to the transfer case is also disconnected but it always pops up as 4x4 on the dash the following day. Please help my dad and I don't know what else it could be. The 4x4 switch keeps blowing out after a few days its our 2ND switch and we don't want to buy another if the problem isn't fixed. I got it from 4L to 4h not sure how it happened.

Check your fuses and relays- how did it blow the switch? You mean it burned the contacts up in the switch?

like the switch just stopped working altogether no night and it does nothing as in when moved into a different position the truck does not respond even if I do it the way the owners manual says

You said in another post that the truck sat for a couple of years correct?-if so, double check all your grounds, even the frame to body grounds- make sure they are all clean and tight. Corrosion/rust makes an excellent insulator!

Dude honestly you're the best thank you!

No, just trying to help- this would be the line of progression i would use- there may be others a little more familiar with the system and might be able to point you to a resolution quicker.
Sometimes it just patience and diligence...
