Hi,

Yes, there is a blend air door that controls the air temp coming into the vehicle. What I would recommend is to simply check to see if it is working. Remove it and change the temp at the dash and see if it moves. If it doesn't, replace it. Also, when you take it apart, confirm the linkage between the actuator and door is attached.

Here is a link that shows in general how one is replaced:

Back with the same issue I have had since I have owned my car: no heat. I have replaced the thermostat, the heater core, did a coolant flush, coolant is bright green, replaced my blend door actuator. So I am pretty sure I know what the problem is I just need tips. I have read online about a blend door “hack”, basically manually turning the blend door in order to change the temperature from hot to cold or vice versa. I am pretty sure the actual HVAC blend door is the problem because whenever I turn the knob to the hot side, I hear very clearly a slip inside the AC box, as if the blend door would not engage all the way. So I have read on how you can cut a hole in the side and stick your hand in there and move it that way. I just need more tips and I need to know if that is an efficient method and exactly how to do it.

Hello,

Yes, I think the blend door actuator is bad which is common. Here is a guide to help you see what you are in for when doing the job:

My only question is how could it be the blend door actuator when I see that it moves whenever I turn the knob from hot to cold and vice versa, the plastic tube that sticks out from the actuator rotates and functions, but I do hear a slip and a knock from what seems like the inside of the HVAC box whenever I turn the knob to hot. Just to be more detailed, I’ve added a video to show you exactly what happens

Can you confirm hot heater hoses right at the fire wall? I have seen where the heater core traps and air bubble which stopped the heat. To see if this could be the problem heat the car fully and turn the heat on full blast then jack the rear of the car as high as you can using a jack. See if the coolant level drops, next jack the front as high as it will go doing the same thing.

Are you refering to the actuator or the door itself? The door really doesn't go bad. The actuator is usually the problem.

To remove the actuator:

First, disconnect the battery. Next, remove the right trim panel from inst. Panel. Remove the electronic blend door actuator connector. Remove the 4 screws retaining the actuator from the heater / evap housing. Remove actuator.

Let me know if this helps.

Temperature control knob controls an electric blend door actuator. Blend door actuator controls the position of blend door. Blend door position determines airflow around and/or through heater core.

You see that big black box on the passenger side? That has to come out. Along with getting your A/C lines loose, and the heater core lines. That big box has to come out, then you can access the door from the top

If you aren't inclined to pull the dashboard, there is a much quicker if less elegant solution. Step 1: pull the radio, cup holder, and trim piece from the dash that the radio fits into. Step 2: drill a hole in the bottom right and top right edge of the duct behind the radio. Step 3: use a rotary tool or sawzall blade to cut between the two holes. Be careful to not go any deeper than you have to. Step 4: cut across the duct from the holes to create a plastic door. Step 5: when you pull the newly created door open you'll be looking directly into the blender box. If the door is attached to the actuator still you can pull it toward you and it should lock into place for heat, or push it away for cold air. Step 6: when you're done, close your access door and duck tape it shut. Reinstall radio.

This is a quick fix obviously based on the blend door not being broken. Dropping the dash is a huge deal, and as far as I can tell, totally necessary to fix the actuator. This option is better than nothing if you need heat or cold in 30 minutes, for free.
