On a 2002 Chevy S10 four-wheel drive, the actuator is typically located on the front axle. More specifically, it is mounted on the differential housing, where it engages and disengages the front axle when shifting between two-wheel drive and four-wheel drive modes. If you're having trouble locating it, consulting the vehicle's service manual can provide detailed diagrams and instructions.

bad 4x4 actuator
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.
On a 1995 Chevy Silverado, the actuator is typically located on the transfer case for four-wheel drive models or may be found in the door panel for power door locks or window controls, depending on the specific application. For the four-wheel drive system, it's usually mounted on the transfer case itself, which is located underneath the vehicle. If you're referring to a different actuator, such as for the HVAC system, it may be located under the dashboard. Always consult the vehicle's service manual for the precise location based on your specific model and configuration.

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")
It is in the front differential housing. Craw under the front of the truck and look at the housing towards the passenger side and you will see it. It will have electric wires going to it.
