What does a front differential actuator do?
The actuator is used to lock the vehicle’s differential together when a switch or button engages the 4WD mode in the cabin. To lock the differential, electronic solenoids engage the actuator gears. This is common in the most recent 4WD vehicle models.
How do you test actuators?
To test a linear actuator’s current draw, simply connect a multimeter in series with one of the leads of a powered linear actuator, and watch the amperage reading as you extend/retract the rod. Based on the reading, you can determine a power supply that will be able to handle that current draw.

Why is my car AC stuck on heat?
Faulty Thermostat A faulty or broken thermostat is the most common cause of your car’s failing heat. Stuck open or stuck closed, the part can not only cause issues with your heat but also your engine’s cooling system. One becomes an issue of comfort, the other becomes an issue of “Oh no, I’ve borked my engine.”

blend door controls the temp by moving a door allowing more or less air to blow through the heater core. mode door controls which vents the air blows through.
How do you test an HVAC actuator?
Here’s how. Consult the repair manual to identify which actuators control the defrost-vent-floor “mode door” and the temperature-regulating “blend door.” Then peer under the dash and locate the suspect actuator on the heater box. Have a friend switch between modes or temperatures while you watch the actuator.
