* Blend door actuator: Controls the mix of hot and cold air. This is probably the most common actuator to fail. Its location varies depending on the Jeep model, often behind the dashboard.
* Mode door actuator: Controls where the air is directed (vents, defrost, floor). Again, location varies by model and is typically behind the dashboard.
* Recirculation actuator: Controls whether the system uses outside or inside air. Also usually found behind the dashboard.
To find the specific actuator you're looking for (e.g., if you suspect one is malfunctioning), you'll need to consult a repair manual specific to your Jeep's year, make, and model. These manuals will provide diagrams showing the exact location of each actuator. You can usually find these manuals online (often as PDFs) or at auto parts stores.
