On 93 S10 Blazer. (things to check)(may/may not be similar to 94) -front axle cable (make sure it moves freely) -vacuum actuator (possibly underneath the battery tray, check it holds vacuum) -4 wheel drive switch (on front axle, check the ball valve on it) -4 wheel drive vacuum switch (on transfer case, ball valve and vacuum) Mine turned out to be a bad axle cable, but it is very common for the vacuum actuator to leak vacuum, thus not engaging the system. There may also be a fuse/relay for 4 wheel drive to check.
check and make sure it contacts, theres not much room behind that button and any play may cause it not to connect, push the dash assembly around the button firmly with one hand and push the button with the other, does it light up and engage
transmission won't engage when you push the button on john deer 155c automatic
sounds to me like your front end is not disengaging, bad actuator under battery.
The clicking sound is your a/c unit trying to engage. I would have freon pressure checked first, if not, a/c unit may be bad
To engage the 4x4 manually (VTM-4), you would need to be in 1st, 2nd, or reverse gear. In those gears and while stopped, you can then press the VTM-4 button, and will engage 4x4. It will only be engaged when around 18mph or lower. Above that, and it will disengage. It will re-engage when it dips down to that speed again. To turn it off, you can just press the button, or shift to a higher gear Keep in mind that even with the button off, VTM-4 will engage occasionally when there's slippage.
Press the 4WD button.

could be the 4 wheel drive module located behind the glove compartment. If you don"t hear a click when you press the button to engage the module isn't working.
do you engage 4WD manually or via the button on the dash? if its the latter then your actuator switch is probably bad. tweek
Clicky pen habit :P - I really don't know - I don't think there is one!
There is a black box located behind a panel directly behind the driver seat on the side of the vehicle. Push the reset (black) button and release it, a red light should light up then go out. Your 4 wheel drive should lock in, IF it is electric shift.
It may be the starter solenoid that is clicking. If the battery is very low when you try to start the car, the solenoid will engage but the starter will not turn. Because the battery is so low, there is not enough power to hold the solenoid closed (in the start position) and try to turn the started so as the starter draws power, the solenoid clicks open, The starter doesn't draw any power with the solenoid open so the solenoid has power to close again, the starter tries to draw power and the cycle repeats. The sound seems to come from behind the glovebox because the solenoid is probably mounted on the passenger side of the engine compartment.
