Thank you for showing the actual removal! Everyone else just says “remove these 2 bolts” and skips to it being out. I was having a heck of a time.

I struggled with the same problem on my 05 Yukon, except it was for the rear AUX heater. After lots of diagnosing and realizing there was nothing wrong with the actuator or the control module, I realized that the feedback circuit that tells the control what position the door is in was out of range. It should read between about 1 and about 4 volts depending on the position. If it reads close to zeor or close to 5 volts then the acutator will stay in the extreme position and will not move. Use a volt meter and measure pin 9 of the actuator, it should be the dark blue wire. If its out of range, remove the actuator, open the acutator and reposition the gear then place something at the stops to prevent the gear or arm from allowing it to turn beyond the extreme ends. Reinstall and initialize the control by removing battery power or the HVAC fuse for about a minute. measure pin 9 and confirm your voltage stays between 1 and 4 volts at the extreme end of door movement. Easy fix but complicated explanation. Oh and the actuator pins start at 5 and go to 10. Pin 8 should be missing if our acuators are the same. Good luck.

Thanks for showing the process of the damn bolts. FYI 7/32 standard = 5.5mm

🙏🏾🙏🏾✊🏾 Preciate the help brotha. Oklahoma is hot today lol did the hack and was back in business 2 minutes later.

Thanks for the hack. I'm having the same issue. I think the mechanics didn't line it up correctly after fixing / diagnosing. Do you think you can flip the door without removing the old one?

In the video I referred to the part as the blend door by mistake, it’s actually the MODE DOOR. There’s a comment below ⬇️ labeled “It’s the door actuator!” In that thread a viewer explains the difference between each door actuator. Hope this helps, if you have additional questions leave them in the comments and I’ll try to get to them expeditiously!

Problem is when you turn ignition off and fan stops blowing that white gear fall back down. You would have to jam something against it or tape it in the position you want.

Thank you brother. You saved me a lot of time and money. Have a great day.

Nicely done. Thank you for the vid! Now, I need to determine if I want to install a new unit, seeing how difficult it is to just remove it.

good video thanks! It can cost $3000 to have the blend door replaced they have to remove the whole dash! The white switch is a great hack, I may tie a wire to mine!!

God bless you. I’ve been fighting with mine.

Thank you for this, I will do this until the actuator comes in

doing the mode door on my trailblazer and no videos showed how to pop that vent off so i could have better access so i very much appreciate it

frickin awesome. got same situation on 2005 express van

Doing mine this weekend on my 04 tahoe thanks

Thank you el mejor video del aire acondicionado aorre mucho dinero biendo este video

Thank you for the help

so the notches on both go behind the flapper on the acuator or in front im confused sorry

Doing this tomorrow on my Silverado

Is there a way to move that white gear into the upright position without taking the actuater out ?

Thanks, great help!!

Great video, bud.

Was it only blowing AC/cold air through defrost? Or was it only blowing any air at all through defrost? Having an issue with my 01 silverado thats blowing hot air on every setting except the defrost setting.

You have me thinking I can really do this 😂 and I’m confident af about attempting something like this. Thank you for this video

My rear vents blow backwards, when switch to top it blows out floor, when switched to floor it blows out top vents 🤷‍♀️ any idea?

When I turn my ac or heat I don't feel no air or hear the blower. What could this beat on my 2004 Chevy Tahoe LT?

Is this the same for 2002 Chevy suburban?

I did the same thing today, you can reach around and do it without taking it apart. Thank you

Thankyou

Anyone having issues with the top screw? I can get my 5.5 mm socket attachment in there, but nothing else fits as there’s a metal plate blocking me from attaching the socket wrench. Any assistance would be great!

It's the mode actuator!

Could also leave the notched part on just replace the main part

Dam bro I’m having the same problem! I’m trying re see the video confusing , my 2003 Tahoe air only blows out the top defrost not the vent

OK. getting the actuator out is the easy part. getting it back in is the HARD PART. And no one gives any guidance on how to do it. Its clear you don't know how either.

Did not even make a 94 bro!
