Very helpful alignment instructions. Turning on the fan to see where to adjust the plate to was what I needed! No other video gave these instructions. I have been messing with this for 5 days now. Can’t wait to fix this tomorrow!
But what do you do when you already f***ed up and plugged it in and ran it without lining it up properly?? Please tell me there's a way to go back and get it timed right.
@@jwalker5175 you'll need to get it reprogram with a scan tool only way or you'll have to buy another one reinstall when finished plug it back in. Plugging it in is the last thing you do
Mine had a 8mm or 5/16 head on the screws. I used a socket in the end of a pair of vise grips to get the top screw. I had to bring the vise grip down and move the socket a few degrees to each time to tweek the screw out. Thanks for the video, the description on how to line up the plate helps.
Thank you! Of all the videos I've watched on timing that door. Yours is spot on! Everyone one else either didn't show it. Skipped over it or vague in saying anything about it. Thx again!👍
Replaced the one in my wife’s 02 Tahoe and when I went to test it wouldn’t work properly I scoured the internet looking for a reasion as to y and came across your video I didn’t have my controls set properly befor install Thanks for the video
How do you know which is face or feet or defrost on the plate. Got a new actuator and it's centered in the middle and my plate is not centered that way so if I move the plate to where it fits originally and have the actuator on with it centered in the middle what mode would that be would it be face?? It's confusing not knowing what line on the actuator is what and where the plate should be positoned
You need to check your vehicle air mode. Turn on your ac without the actuator hooked up. This will help you figure out if it's on defrost, feet, face or whatever. Put the plate in place without the actuator, again the actuator should not be plugged in. Turn the plate by hand and see if the plate allows you to switch to all modes. Once the plate switches to all modes you should be able to install actuator and line up screw holes. You should not hook up the actuator until you know plate is aligned. If you do, you could cause the actuator to stay out of time and it will be ruined, so, make sure it's in place correctly. Hope this helps.
Replacement part number is dorman 604-113 also remove the feet vents from driver side and the one on the middle it give your a bit more room to work also fit your other hand inside of the vent were the air would bloow out for feet and u can move the white lever's with your hand and it can go on so much easier
Thank you Brandon, the video was GREAT! My truck was doing exact same thing, except for some reason, the mode door actuator was just stuck. I was able to slightly move the mode position gear that engages with the drive gear, adjust control knob to different modes successfully and that seemed to free up the actuator. What a nice surprise! Your video was a tremendous help!
High, I'm having a similar issue. I've replaced the actuator twice and it works for 5 minutes and then locks up. You say you freed it by forcing the gears to move?
When you remove the actuator with the cam “plate” the 2 white levers move and not that easy to figure out what position they have to be in to line up the new cam. This video doesn’t show this, he just shows it already installed
Quick question, my blower is stuck on the dash vents, so should I set my switch on dash vents, pull out my old actuator then adjust my new actuator to match it before I install it?
I've tried 3 different actuators. 2 of them when powered on go to defrost when I turn the selector but say stuck there. The other actuator works but clicks non stop when selected to defrost. What the hell is going on?
Watch my video. I go thru steps of ensuring how to install actuator at right position to the air mode selection. You have to make sure the actuator is in right position for the mode selection to open in all positions. Hope this helps.
Glad we could help with your part replacement. This was the intent of why we made the video. There was nothing out there that really describes how to do it. Thanks
Hey Brandon, mine is stuck on a/c face vent only. It won't switch to any other mode. I can't even get just a bare socket onto the top screw for the actuator. How did you manage to squeeze that elbow adapter in there? Are your sockets Xtra short or something? I tried also with a universal swivel adapter and even that doesn't fit.
But what do you do when you already f***ed up and plugged it in and ran it without lining it up properly?? Please tell me there's a way to go back and get it timed right.
Now you are saying to move the plate I guess yours was pointed at the feet mine is pointed at windshield for defrost so do I have to move it to the defrost To get it in
I have some questions and I hope you can help . My plate came out too. The actuator is lined up in the middle like yours. BUT where is the white gear and the white pin supposed to be positioned? In order for the motor to line up with the screw holes, the middle position on the motor forces the plate to revolve all the way to the right. This doesn't make sense. The plate should be in the middle somewhere, shouldn't it? Not one one of these videos show where those two items should be located in the middle position. Mine stopped on defrost. How now can it be in the middle? It should be a simple job, but I'm a big fellow and getting my hands up in their is not easy.
I'm sorry just saw your comment. Did you figure it out? The actuator should come with the white pin aligned to the middle position. If not, something's not right. Did you plug in the actuator and turn mode switch? If so, the actuator is out of time and cannot be fixed. You will need to throw it away and buy another one. They cannot be fixed after they are out of time. Also, make sure the white gear is put back in right location. It can be installed out of time. You want to put the white gear back on with the mode switch in the feet position which is straight up. If not the actuator will not line up with the screw holes. Hope this helps
@@jerome0073 how do I do this?? I know nothing about this and I'm trying to replace mine on my own. I messed up and did it wrong so I have to figure out how to get it timed correctly now.
For those of you who have a 99 Tahoe, this job will take literally 10 minutes. The only thing you have to remove is the actuator. Nothing was in the way.
Sorry, I missed your question it appears from a few weeks ago. Removing the actuator from the plate is a bit difficult. I just gave it a good yank and it came out without breaking. I can see where some might break there’s trying to remove it. For this case, if you remove plate and actuator together, you now have it outside vehicle and can gently work to remove the actuator from the plate. Slow and easy. Hope this helps.
doesn't have to be that complex and if it stuck is defrost, how did it get to center without something moving as they always default to defrost..... simple job... I'm a 67 year old lady and I did mine...
+Nancy Olsen thanks for the feedback. I agree it's a simple job. The door gear piece came out with the actuator on mine so I described how to get it back in place and timed right with the actuator.
It’s a right angle extension for a socket. It fits 1/4 inch sockets. It came in a 1/4” socket set I have. It fit just right in that tight spot to loosen screw.
Yes, just that one setting, where the arrows point to tge head and feet, the air comes out below only, turn the knob to where the arrow points to the head only, it comes out of the dash, then turn the knob to where it points to the feet only, it comes out at the floor only, the defrost positions work ok, and I replaced the switch and selector panel with a new one, so I don't think that could be it. Thanks for the quick reply!
It sounds like the selector plate which mounts to the actuator is out of time. This could be for various reasons. 1. Plate is damaged 2. Actuator was installed out of time with selector plate. 3. Actuator is working intermittently and needs replaced. The selector plate is what moves the door that sends the air to your various settings. You could remove the actuator from under dash and turn on ac while moving selector plate to see if it's the plate or actuator. If you remove actuator make sure it is disconnected from electrical harness before turning on ac and operating the controls it will ruin the actuator by causing it to get out of time. It can't be repaired once this happens, you have to buy a new one and start over. Hope this helps. Good luck!
@@brandonburns7337 actually you can re-zero by taking cover off actuator and lift and align main gear with center position of potentiometer gear (dots on pot gear help). Take an old one apart and you'll figure it out.
I used an "elbow" socket attachment that came with my 1/4" nut driver set. It is small and allowed me adequate room to use a socket to remove the screws.
Nobody warned me...after unscrewing the acuator..when I pulled it out. THE WHOLE WHEEL THING COMES OFF with it..the wasnt the best time getting it back with the right index...😫
Mine did the same this is why I described within the video how to get it back with the right timing. Maybe the video helped you with the replacement. Appreciate your feedback.
Hello Gary, not sure what you meant by sound would be nice. The video has been loaded for several months and I haven’t had any comments about the sound. Lots of positive feedback for this so just trying to understand your comment. Thanks
Great video Brandon , if that other piece of duct work would come off , it would so much easier , I used a socket on my 1/4 in ratchet for that upper screw and I cheated because I left the wire fastener off it , but I found out the key piece to this job was to time the white gear to the black plate , Happy Motoring at the ESSO sign Frank T

Thank you for taking the time out to show us this
Thanks for help but may I suggest holding phone sideways so the picture is bigger and full screen.
What does it mean,(it only goes to two dots,what dots?
Thank you for making a video that actually explained things properly and how to do it. I avoided a lot of frustration by watching this first! Thanks!
Glad this helped you out with yours.

you saved my bacon today sir! matching the plate to the setting and putting the actuator in last was genius!! works perfect!

Thanks Brandon.. fixed mine with this explanation.. Seemed so logical when it all clicked
@@brandonburns7337 What if its with a automatic system and not a manual system?
Thank you for sharing. Your knowledge on alignment was very helpful.

Thank you for the video. Good grief that thing is hard to get to! By the way, a 7/32 socket will work in lieu of a 5.5mm.
No mention about the 3 door levers that have to be reinserted into the cam...arguably the crux of this job.
This is exactly the issue that we are having. Thanks for posting. I'll purchase the part. It comes setup in the middle setting...perfect.

THANK YOU THANK YOU FOR POSTING THIS UP🤙🏽
Thanks, I will be doing this soon.
While he says you need a 5.5 mm socket I used a 5 mm and it worked just fine with a 1/4 inch rachet with extensions.
I found that a 7/32 socket fits perfectly.

Thanks for the video. I suspect this is the same issue I have with my '99 Sierra 1500.
Thanks for the great instructional video! But the image stabilization software makes me feel like I drank too much and might hurl.
Just get your die grinder out and notch the bracket so you can get a nut driver in to that top bolt
Your my kinda tech! A real flat rate’r.😊
thanks for the video will take on this task on my 02 chevy silverado
Let me know how it works out for you when you replace yours. Thanks
Not a GM guy at all. But darn daughter is. Thanks this video made it very easy to replace.

Went thru the pain staking process of replacing mode actuator and the truck does not appear to calibrate it. Is there a calibration procedure?
Thanks brother...

I’m using a 1/4” socket set you could get from Walmart. Sockets are short.
Worked for me thanks
Not to sound too crazy here but for the upper actuator screw maybe using multiple U-joints on a ratchet might help for access?
Yes this would be a way to get the screw out as well. Good suggestion!

Do you have to line up the little white gear on the black gear or is it lined up as long as your bolt holes line up
Yes, the white gear needs lined up with black gear when putting on actuator. In the comments is instructions on how to do it and also in video.
