Good post and nice job! I just went to my first "actuator rodeo" on a 1998 Pontiac Grand Prix with the dual-zone HVAC system. Of course, it was the driver's side that needed to be replaced! Not very easy!

Excellent tip! Thank you very much for showing us the inside of each one of them! It seems that the big gear is the weakest link! My hat off to you! Keep them coming!

Bro you did it! I was ready to give up and watched your video about grease being on the little sensors below the gear. I took it all apart like bill nie the science guy thanks to you. I got something backwards and it now moves but does not correlate tothe screen but who cares your the man broski

Had new Dorman one clicking. Couldn't figure out why it wouldn't reset. Set the gear center at 120 count, but always clicked around 40. Swapped the Dorman gear with the broken one in the OEM and it reset with out gears skipping at 40. Guess the cheap Chinese gears aren't good enough. Wouldn't have never thought about just swapping the gear without watching this video.

Thanks - I forgot about Dorman ○ just removed the glove box and looked; Need to know why and how the 3-wire effects positioning • Per your report it may be a tooth on the gear ~ maybe I should watch the video huh?

Brian, I replaced all of the actuators in my 06 Dakota w/Dormans due to the clicking noise. I tested each actuator on the bench before installing. Should I have aligned each actuator before I installed them because I having trouble again?

Great explanation so the recirculation one is what would cause my climate control to stop switching to defrost to front vents or floor? My 2000 Nissan Altima only blows air from front vents & doesn't switch to defrost or to the floor when I push the buttons... Thanks in advance if you have time to answer my question 👍

Didnt he show at the end the split in the gear which makes for a wider spacing and that's what fails in the actuator? I pretty sure he did then he proceeded to put that same bad gear with the split back into the factory actuator and calls it good? What did I miss there?

+Gristle Von Raben Isn't it possible to place the wheel in different location on the shaft? I thought that gear wheel was not rotating full 360 degrees. If so, you could orient it such that the repaired teeth would never have to mesh.

I must've heard 5 different interpretations of how to align the potentiometer (blue gear), none of them are consistent with each other. How do you know you are correct in aligning this gear?

@punabuilt808 4 жыл бұрын

You can test the resistance output of the potentiometer (blue gear) to know when it is aligned properly. Test resistance between pins 7 and 9 and pins 9 and 10, turn the blue hear until resistance is the same at pins 7 and 9 as the resistance on pins 9 and 10.

@@punabuilt808 Thanks for the reply. I actually just ended up finding one in a junkyard and taking it apart to see its relative position. Here's a problem I'm having now though: I cannot get these actuators to recalibrate! No procedure I have used on the internet has worked. Because I fear burning out the motor, I have left both the heat and the mode in the vertical position on my hvac control. Any ideas? Car is a 2000 GMC Yukon 5.3L SLT

@punabuilt808 4 жыл бұрын

@@sawmaster6095 I wish I could help but I'm having the same problem. Changed the mode door actuator and both blend door actuators but no matter what I do it will not calibrate. If I unplug the HVAC controls instead of the HVAC fuse it calibrates and works for about 10 minutes then it defaults to defrost and is unresponsive. I also installed a brand new HVAC control module and nothing works. Really makes no sense. I gave up and ate the cost of parts. Sent my customer to the dealership so they can calibrate the chevy tech 2 scanner :(

@sawmaster6095 4 жыл бұрын

@@punabuilt808 Well guess I'll take mine to the nearest dealer too. The design of these things is crazy to me! For starters, it shouldn't use a potentiometer for positional feedback, it should use a Hall effect sensor! I mean come on it's in a car, which vibrates all day long, the thing's bound to get out of wack! And why does it have a million little plastic gears? If it were up to me, I'd use a stepper motor, Hall Effect sensor, and do away with all the black-box digital crappage that makes these things impossible to fix!
