Peterbilt 579 defroster no air fix.(HVAC system, blend door and actuator troubleshooting & repair)
HTML-код
- Опубликовано: 4 дек 2024
- The defroster vents were not working. I removed the whole dash in this video. The HVAC system, the doors and the actuators are clearly visible in this videos. The panel door was the problem. It was broken, so i replaced it.
It’s 2021. My 2016 Peterbilt stopped heating. It turned out the cold/hot blender door Actuator had a loose mounting screw.
I got access to it by simply removing the two dashboard plastic covers, behind the air brake valves. I tightened it with a T20 Torx wrench and it started working again.
I learned a lot from your video. I hope someone finds my experience helpful.
About to try the same thing. I hope it's as simple for me.
I would like to take a moment to THANK YOU for this video....you spent a lot of extra time stopping to take clips and explain in enough detail, including IMPORTANT little things like the fact the plastic panels have to come off in a certain order or you will break them..... this, for me, is the difference between a helpful video and utter frustration!! I guarantee you saved me at several hundred dollars in broken parts, and I feel confident in doing the exact same repair on my "16 579.
your pride in your truck is clearly shown, and you should be proud of that, as so many in this industry do not have that sense of ownership, and their trucks reflect that
Again, thank you so much!!

Best you tube video ive seen yet on not over explaining and getting str8 to the point
Hey thank you so much for this video, just got out truck back from a shop I had never been to before and got the bill for $1,800 labor, and about had to sit down to write the check. 😵
So feeling much better now after watching your video!
Thank you, thank you, thank you!
Blessing!
Thank you for this video you helped me a lot may God Almighty bless you
really smart guy and courageous to do it by your self
Thank you sir, I can’t thank you enough!! I took mine apart and I have the same issue. Hope they stock the door here in Vegas!
Damn!!!!!!! Good you saved thousands.
Thats too much for me to handle.
Great job
Really wanted to see you open it up! Great video helped alot!
Awesome video helped me to find exact same problem as yours with same issue with broken panel. Everything still apart and ordering parts. Makes me think this is a PACCAR design flaw and waiting to happen with every truck. Yes it was stressful but glad I did it.
Thankyou
Thanks for sharing this... Great video...Helped me have the confidence to replace my broken blend door and actuators
Thanks for the video. My truck started doing the same thing. Argggggg.
Great job!! Thank you for posting this video.
I just replaced the blend door actuator for the 2nd time in less than a year on my 2016 Pete 567. The problem I'm facing now is when I set the climate control to anything less than 84° I get ice cold air, when it's on 84° I get full hot air there's nothing in-between I'm trying to figure out where to start troubleshooting the issue after watching your video I'm thinking I need to get my hand in there and physically check the blend door. I've had a tech tell me there's also an update to the cab controller for this issue as well
Good work. Looks like a few hours just to get to it.
Thanks for the video thats very helpful, do you have any chance vent door part number?
Thanks for sharing that very helpful!
big job man😮
Have the exact same problem. I appreciate the work you put in. And thank you for sharing. I think I will sit down and do the work myself as well.
My question is do you have part never for the vent door you replaced? My pin is also broken at the actuator. So I will be replacing the same part.
Thank you so much for the video got the same problem
Did you have to reprogram the motor once you put it back together?
I tell you Peter built quality has really went down the tubes seems like all 579s are having all kinds of problems. And to make matters worse you have to tear basically the whole dash out to to change a few little things that should last at least a few years.
Nice I have some problem with 2015 Kenworth T680

Part # F31-1170-06
My truck it's a pet 579
But I get that blend door from Kenworth dealer..
Just so I'm clear, Kenworth sells just the Door and not the whole assembly like Peterbilt?
What's the part # for just the door?
I'm in Kenworth and they said I need to buy all part
Awesome video helped me to find exact same problem as yours with same issue with broken panel. Everything still apart and ordering parts. Makes me think this is a PACCAR design flaw and waiting to happen with every truck. Yes it was stressful but glad I did it.
