Heating issue

Hi everyone, I am new in this forum. I have been reading this forum for a long time and i now finally a member. i hope I ask the right questions so someone can help me out. I just picked a 06 rsx type s a few months ago and she is sitting on my friends driveway. I just found out that there is no Heat. I came across that there is a plastic that looks like a servo harness that broke off underneath the dashboard on the driver side which has a piece of rod that controls the blenddoor. Can anyone tell me where I can get the plastic part? Do I have to buy the whole unit? Thanks you in advance on any inputs.

Yeah, it looks like the air mix control lever cracked and fell down where it is in your picture. You have to buy the whole motor, unless you have the ability to scan and 3d print the lever. The part number is 79161-S6M-A41

Before you go getting a replacement, make sure the air control linkage moves smoothly. If it doesn't you'll need to try and repair the air mix door. If it can't be fixed, just get a replacement heater unit which will likely be used and include the air mix control motor.
If pulling didn't seem to move it, did you try pushing it? If it doesn't move then that's probably why it is damaged like that. Getting the heater unit out will be a PITA, but it sounds like that may be your next step to better diagnose what's going on and how to fix it.
Oooh, envy! My '05 Type S has same issue, so did exactly the same as you, but to no avail. My blend door is extremely difficult to move. I've no idea what is jamming it up, but it absolutely will not move freely. Worked fine for years, then suddenly...

I'm in SoCal High Desert where summertime temps are typically triple digit, and winters get below freezing. Removing the bloody dash to get to the blend box is just not worth the trouble (at least to date) as I typically run the AC all summer and heat only in winter.

When it's time to switch, I slide under the driver's side dash and with key on, turn the temp control to either full heat or cold, then manually twist the blend door gear to "help it along"... It does not move easily, but does move. PIMA, lol... One day I'll sort it all out properly.
Maybe the hing where the door attached to the heater unit needs a little cleaning and some fresh white lithium grease?

Maybe try using a scope camera to get a closer look at things?
