Where is the blend door actuator location on a 2000 s10?

your on the right track! your blend door is broken or your blend door actuator is broken.

You can check the hoses and pipes in the engine compartment after you run it, check for condensation or cold pipes near the firewall. Of course you need to turn the engine off to eliminate the danger of checking it with your hands. There is a mode selector and a blend door that selects hot and cold air. These are inside the cab near the fan motor and it is the blend door that you are going to have an issue with if the pipes are cold and the air is hot. There is a blend door actuator and it could also be the door itself is stuck or broken off. It would be nice to know the make, model and year to tell you more.

Feel the heater hoses where they go through the firewall. If they're both hot but you're not getting any heat, your blend door is not moving to mix heated air with unheated air. It could be the blend door actuator not working or the HVAC control unit not working.

CHECK THE MODE ACTUATOR ON DRIVER'S SIDE

There are electric motors that move blend doors in your dash board. The blend doors control the heat/cool ratios as well as the location the air will blow from. It's very common for the doors to break or the motor to fail and require replacement which can be costly.

Air Temperature Control Blend Door Failure No Heat or no AC (dependes on where door sticks)

In all modern cars there is a tiny DC electric motor driven gear drive that moves a plastic door that blends heated and cooled air from the AC and the heater core, this is called (interestedly enough) the air temperature control blend door actuator. The motor that moves this door fails because the door starts sticking from warping, most common complaint is no heat but it can be no AC as well. To replace these parts (blend door and blend door actuator) you must remove the entire dash from the car. Always have this problem confirmed by a dealer or qualified repair shop as it is a very expensive repair.

Other causes of no heat in the cabin are engine thermostats that are stuck open (engine runs cold) or air bubbles in the cooling system.

Hi!
If the Temp. Selector Control is set to Heat and blows cold air, your Blend Door Actuator may be stuck or it is inoperative. The actuator is not fixable, if it fails, it must be replaced. Follow the instructions to remove and replace it.

1. Disconnect battery negative cable from battery and properly isolate to prevent accidental reconnection.
2. Remove the instrument panel.
3. Disconnect the electrical connector from the blend door motor/actuator.
4. Remove the four screws holding the blend door actuator to the plenum.
5. Remove the temperature blend door actuator.
