What does the actuator on a 4 wheel drive do?
The actuator on a 4-wheel drive allows the vehicle to shift into 4-wheel drive with the push of a button or a shift of a lever. The actuator allows the front axle to become engaged.

Differentials were locked by vacuum pressure on a actuator on the front axle, if there is a problem with this actuator or with your vacuum system the front axle will not engage. You may want to remove the acy=tuator and clean it out, ot locate the vacuum leak in your system.
Why won't 4 wheel drive engage on 94 jimmy Push button and hear clicking sound behind glovebox?
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.
Why wont your 2001 Chevy Blazer kick into 4-wheel drive you can hear it switch over the but the light just blinks on the dash and wont lock in to any four wheel drive?
It will either be the vacuum solenoid (actuator) located under the battery tray or the electronic solenoid on the front differential. Most commonly it is the vacuum solenoid (actuator). Once you take the battery and battery tray out you will see the rubber bladder of the vacuum solenoid (actuator) if it is torn or busted replace it. Check the vacuum solenoid (actuator) located under the battery and battery tray. It could also be the vacuum solenoid located on the firewall above the distributor (approx. 3"x1")

Connecting the vacuum line to allow the four wheel drive to kick in on a 1988 S15?
At one point while offroad I had the vaccuum lines for the four wheel drive fail. If you go to the intake manifold, there should be a few ports that are blocked off. With the vehicle running unblock and check for vacuum. If you have vacuum, you can connect an extra bit of vacuum line directly from the port to the actuator that engages the front right axle shaft. This effectively bypasses the vacuum switch on the transfer case.
