They slip at about 25 to 30 % of what the actuator motor produces. Which is plenty to turn the blend door, and not so much to start chewing away at the hex spline points. I designed them to be somewhat rounded, and they are made of nylon. My original designs when I first started to find a solution would either shear the PLA (before I switch to nylon) or would start to eat at the points. Hence I looked for a torque reducing design. Nissan detects when the motor stops, by a reflective electric signal. So the actuator will go for about 1 or 2 seconds after the blend door stops. However, they also stop if the motor stays on for some pre programed time. This only happens when they want to zero the position. So the slipping lets it still zero at the blend door stopping point. Also wanted to mention this is spring loaded, that is what allows it to slip over the rounded intersections.
Update: one of the screws didn't fit in completely. The issue was resolved after tightening that screw. Thanks to Chris for providing offline guidance for fixing it.
This fix will let the blend door function even if stripped. Download the instructions to see if this is your issue and if this fix will work. www.unique-engineered-products.com/how-to-install
What drives me nuts about this video and the other one with the $350+ kit is that neither show what is admittedly the hardest part of the process, removing the foot vent. Yours says "pull the vent out." Really, how does that work? I'd be grateful for a bit more help with the toughest part.
There is more detail on page 7 of our pdf instructions. This download is on our website linked in the description. Remove the phillips screw closest to you. • Use something to pry off the top part of the vent latch. • Pull the vent out, while the second screw is still attached. • Now you can manipulate the vent in a position that makes it a little easier to get the second screw. • Remove second screw, I had to use a phillips head on a 90 deg bent driver. You could probably get it with a small ratchet with a phillips end. • Put the vent aside, you will not reinstall this piece. The air will just blow from the location you removed it.
it worked magically. thanks for this fix. I ordered it from Canada
This is exactly what I need. I have to tear under my dash tomorrow to get some heat before I can’t defrost my window this next week.
Can I please order this?
Absolutely! Check the link in the description, and we ship next business day.
So the small pointed teeth that mate up both sides won’t strip out easy also? I’m not sure how much torque this is under. Thanks

@ Okay thanks, I’m going to watch your video again. I have to make a decision soon, my wife is losing her patience, lol! Thanks
How do I order this door vent actuator modification kit
Yes, this kit is for sale. The link is in the description, and we ship next business day.
Are you manufacturing this kit to sell? If so how do we order?
Yes, this kit is for sale. The link is in the description, and we ship next business day.
my blend door moves intermittently/rarely after multiple attempts of moving temperature up and down. could that also be due to the stripped shaft?
could be
I started to see this problem back again a few days after fixing it with this kit. What could be the issue?
Please contact us through the website. Sounds like the space might need to be a little closer. We can work with you to figure this out!
@Unique-Engineered-Products-x9i thank you. I will contact you through your website

So if the plastic tab is stripped bad . Will your kit still able to turn the door ?
This fix will let the blend door function even if stripped. Download the instructions to see if this is your issue and if this fix will work.

Will this work on the mode actuator as well?
Not sure what you mean by "mode" actuator.
@stephanienoack4708 the actuator that changes the air flow mode. Defrost, lower vent, front vents

Remove the phillips screw closest to you.
• Use something to pry off the top part of the
vent latch.
• Pull the vent out, while the second screw is still
attached.
• Now you can manipulate the vent in a position
that makes it a little easier to get the second
screw.
• Remove second screw, I had to use a phillips
head on a 90 deg bent driver. You could
probably get it with a small ratchet with a
phillips end.
• Put the vent aside, you will not reinstall this
piece. The air will just blow from the location
