I know how a lot of viewers like to put down dealership techs on not fixing their vehicles or the cost of getting them fixed. The dealership sets the labor rate per hour not the tech. The tech gets about a quarter of that and the dealership gets the rest. If a dealership tech was to replace the right side temperature actuator under warrantee, he or she would only get 2. 4 hrs to install and 0. 3 hours to diagnose not 6. 9 hrs which is more realistic. So if it takes 6. 9 hours, if everything goes smooth, and you only get paid 2. 7 then you are working for free 4. 2 hours. This is only one instance of many a dealership tech getting under paid goes through each week. If there was only warrantee work, a dealer tech could not make a living. Sorry for this rant but I had to bring this up so maybe the viewers could take this into account when they bash a dealership tech the next time.

I know this is an older post, but had to say something. I have found on many of these vehicles that use this type of blend doors that if you disconnect the battery, when you hook the battery back up and start the vehicle, the vehicle has to relearn the positions of the blend doors. It does this by slamming the door back and forth between the 2 end stops. That is what usually strips a tooth or two off the gears. Those plastic gears get brittle with age and break easily during the relearn. When you put the new parts in, the plastic isn't as brittle and usually will survive the relearn. Don't go to the junkyard for a replacement because it is an older part with the brittle plastic and will just destroy itself when installed. I know this from experience.

This really chaps my hide! Incorporate crappy parts that fail at abnormal rates and they will claim theyre just giving the customer what they want. Not this customer. And what about the cost to replace the other one at what, 95 per hour plus a 200 part for a lousy door control? The last Chevy I owned had paint flaking off with the primer showing through in huge patches on a gutless 305 C10. And the taxpayers later bailed them out in the financial crisis. Which makes me wonder, if we should ever get into another depression and war can a vehicle be made to run without an ECM made in China and no longer available? Or would you be the proud owner of a 3000 pound paperweight?

This infuriates me. 200 for OEM? This is essentially an RC car/boat/plane servo but has positional feedback? These things were 25 or less for RC cars when absolute position servos were BRAND NEW. THIS is what is wrong with the automotive industry. And please, let no one start with the diatribe of, Well, they have to be more reliable than typical consumer goods, bit. I work in the industrial sector and know that MIL Spec gear that can accomplish this is 80% (plus) less expensive for the same application (And has a better failure rate.

Sooo, I have an 05 Silverado with the dual auto temp control. The temp sometimes goes full hot when full cool is called for on one side or the other. If I disconnect the battery and turn each control, one at a time to full hot then full cold, it goes back to working normally and controls correctly for a few months. I'm guessing this system is similar to the video vehicle system, with thermistors used for temp feedback. I don't have an Autel. Without resorting to a Parts Cannon, any suggestion as to the likely culprit?

When you removed that black gear we could see the black resistive material on the circuit board that the wiper wipes. And I'm guessing that resistive material is worn out on the cool end. It's exactly the same as a scratchy volume control on an old stereo system. The wiper can only wipe the resistive material so many times before it starts to wear it away. And there ain't no fixing it except replacing it as you did.

So 6. 9 book hours on a right side passenger side actuator on the Silverado could be an indication that I don't need to be in a hurry to work on my 2000 Corvette that is displaying a code for the passenger side actuator. Now I'm thinking that listening to the wife whine would be less expensive than actually replacing the door actuator.

A lady friend I had the hots for but wouldnt tell her cause she gets a big head had climate control stuck on hot in the middle of the summer. Could hear that click click going on under the dash. Thankfully only had to ride in her car with two other people only once. Longest hour in this guys life

Pin 6 of the actuator has 2. 5v on it at rest. To command the actuator to move, the HVAC module applies 5v to pin 6 for the actuator to move in one direction, and 0v to pin 6 for the other direction. The actuator also has a 3 wire feedback position sensor as well as a 12v ignition feed and ground.

i got to do mine on my chevy which is no big deal but do i need to calibrate the new one since i am a truck mechanic i dont have a scanner like what you have i just have a basic one that reads powertrain data so will i need to go to a car shop to have them calibrate it?
