1991 Mazda B2600 Question: it is stuck in 4h

I have a 1991 madza 2600 i thats stuck into 4 high and will not go into 4th gear -
Answer 1
Manual transmission will not shift into 4th? Is this a push button 4x4 system - electronic? Or a manual lever pull? If it is the push button, the motor that switches the transfer case position could be failed. -
