So, what is an actuator in a four-wheel-drive vehicle? When you engage the 4WD mode on your car by pressing the button or switch (depending on your car model) in the cabin, the actuator locks the differential. The primary function of the actuator is to lock the differential to activate the 4WD mode on demand.
TRANSFER CASE ACTUATOR
The GM Genuine Original Equipment Transfer Case Actuators are electric motors that perform transfer case shifting in electronically controlled four-wheel drive systems. They are located on the outside of the four-wheel drive transfer case housing.
The Axle Actuator is a device which activates the front axle when the driver switches from 2 wheel drive to 4 wheel drive. When the switch is turned on, the control module turns on an air-pump which is mounted near the front of the car. The pump begins to build pressure and eventually opens a relief valve.
If your blend door actuator has gone bad in some way, it’s basically one of two problems. … If that happens, the blend door won’t work, and it’s likely your temperature will just be stuck on one setting with no ability to adjust the intensity up and down, or alternate between things like the lower vents or the defroster.
When the actuator is bad, you will experience problems with your 4WD mode. When this happens, you should have your actuator checked or repaired immediately as this will cause a loss of driving efficiency. In modern 4×4 vehicles, the actuator stands out as one of the most critical components of the 4WD vehicle.
An actuator is a device that uses a form of power to convert a control signal into mechanical motion. … Industrial plants use actuators to operate valves, dampers, fluid couplings, and other devices used in industrial process control. The industrial actuator can use air, hydraulic fluid, or electricity for motive power.

If the transfer case fails during operation, the vehicle may be left permanently in neutral or the transfer case may bind. If the transfer case is malfunctioning electronically it can cause erratic shifts from high to low gear and from two-wheel drive to four-wheel drive.
An electrical fault such as a corroded wire or faulty 4WD dial/switch, A component failure such as a faulty transfer case module or actuator. A seized differential caused by poor lubrication. A leak in the vacuum hoses (older traditional 4WD systems)
Actuators work behind the scenes in vehicles to convert energy into a physical action or force. They perform a variety of performance and convenience functions, from controlling the throttle to directing airflow in the climate control system, and operating power seats and liftgates.
You can. The blend door actuator doesn’t affect your car’s performance or safety, so you can definitely drive with a bad blend door actuator. However, you might notice your air-conditioning system not working properly. … Your passengers might complain profusely at you for not fixing your car’s air-conditioning.

If you can stand the discomfort of the climate control not working correctly, there’s no reason why you can’t continue driving with a faulty blend door actuator.
The cost of replacing a door lock actuator is likely going to be between about $180 to as much as $700. On average it seems like most cars that have a problem with the door actuator are going to end up costing around $200.
The AC actuator is located above or below the coil. It can be set to either single speed or variable speed. When it is not working properly, your AC will be ineffective, and your power bills can skyrocket.
Actuators are an essential part of electronic control systems in passenger cars and commercial vehicles. … Most actuators are electric motors or electro-magnetic valves. They adjust flaps, for example, regulate the flow of fluids or actuate pumps to build up pressure (e.g. in brake and steering systems).
Blend door actuators are the most common reason for the car air conditioning to blow cold air on one side and hot air on the other. … If it does not move with the adjustments and commands, there is a problem with the blend door actuator and it will need to be replaced.
On average, a remanufactured transfer case costs depending on the make and model of your vehicle. The cost of labor to install it is in addition to the price of the unit and will typically run between $400 and $800. Transfer cases can be purchased through Autozone and Advance Auto Parts.
Difficulty changing gears – Low or dirty transfer case fluid can affect your transmission’s ability to shift gears. It can also result in your car unexpectedly falling out of four-wheel drive. … This will create loud grinding noises which may become louder when four-wheel drive is engaged.
Cheap way – To clear the codes and reset the computer, pull the 5 amp TCCM fuse, located at the bottom of the fuse box. Wait at least a half hour, and then replace the fuse. Turn the ignition key to run, wait for the 4×4 lights to blink, and then turn off. Repeat 5 times, and then start the truck.
When your transfer case goes bad, your car might jump in and out of 4-wheel drive on its own. This indicates an inability to stay in a drive mode which can damage the transfer case, other systems on the vehicle, or cause an unsafe driving situation.
Get a tool that will turn front output yoke on transfer case and see if it is solidly connected without slipping to rest of drive train. (jack up rear wheel first and see if you can turn it with tool on front output yoke — 4WD engaged of course.) The results will tell you if it is good or not.

Two-wheel transmissions have no transfer case. However, some vehicles like the two-wheel drive Ford Bronco II, have a dummy transfer case to ease conversion to four-wheel drive by only requiring a new output shaft.
It is under the hood, usually on the driver’s side.
How to Test: If you want to test your 4-wheel drive, then put your car into 4-wheel drive and then turn the front wheels, left and right, while driving in a tight circle at a very low speed. You should feel them bind up if 4wd is working.
