Depends on what exactly you have. If you have a push botton, you can just push the 4HI botton and you will be in 4-wheel drive in high gear. If you want 4LO you have to put the tranny in Nuetral and then push the 4LO button. On some models you have to be in 4HI before you can put it in 4LO. If you have a standard shift transfer, you have to put the tranny in Neutral before you can shift the transfer into 4HI or 4LO. If you have manual lock-outs on your front hubs, then you must put BOTH the tranny and transfer in Neutral, then lock in your front hubs, then put your transfer in 4HI or 4LO.
The Owners Manual sez to be in Neutral when changing from one mode to the other.
If the automatic 4x4 works but the front hubs do not engage in a 1994 Ranger, there is no 4 wheel drive. The transaxle for the 4 wheel drive has to be repaired.
If the button is not working, might be a vacuum line problem. Vacuum lines engage the 4x4, might need to check the lines to the 4x4 transfer case.
It should already be in "4x4" mode if it is AWD
Are you in neutral ? No in reverse.
Only if the van is a 4x4 too.
Lock your hubs and put the car in neutral, then push the 4X4 button, same thing with low range
Drop down to lower gear G2 or 3 and then press 4x4 button
yes
The 1994 Nissan 4x4 2.4 four cylinder has a timing chain.
To engage the wheel for 4x4 operation, the selector should be set to the "Lock" position.j3h.
turn on the engine, shift into neutral, engage the 4x4, shift into drive.
