Perfect video, very easy to follow. Thanks!!
glad it helped you
Best instruction video I have ever seen...thank you
Amazing instruction video, I was able to replace mine with your step by step video I now have great AC on both sides.
How long did it take you?
Excellent instructive video I just fixed my 2014 Chevy Silverado ltz. Because you thank you 🙏
Thank you 🇺🇸
Thank you. You are a legend
This was an awesome video thanks
Glad it helped you
I just repaired my A/C automatic blend motor assembly by disassembling the unit, inspected the gears, inspected the large final drive gear and its copper fingers that slide on the variable resistor pad. I put more tension on the copper fingers and used the surplus lube from inside and applied it to the gears. Reinstalled the unit and started my 2012 GMC Sierra with the A/C on, varied the temp setting cold to hot and back again, IT WORKS! Just my time and no parts.
Great Video Phillip, Can you please tell us what type of Scanner you use? I bought the MDI2 module but like you software better.
I'm using a Snap-on Verus Edge scanner. That's my main go to scanner and what I was using in this video. It's 12K can.
Thank you
Glad you found it helpful
One thing I noticed when your first reprogrammed it, when you went to check if there was a code. That code said “History DTC” meaning it was stored before the reprogramming, maybe if you cleared it then checked again it wouldn’t of have popped up again?
That's possible for sure.
Does this apply to a 09 Chevy Silverado also? Bc my driver side is blow hot then cold.
Is it setting any codes in the HVAC system. It could be the same problem.
I have a question I’m having the same problem with the driver side, receiving warmer air and the passenger side having nice cold air. I will try to do what do you have shown us in this video. My question is when driving around the city without the Aceon I feel warm air coming through the vents of the driver side and not the passenger side. Is this the same issue
Yes likely the same issue.
@@PhillipBailey Job completed, and everything appears to be working as it should thank you for taking time to post on how to fix it on line. Saving money always a good thing.
What computer program did you use during this process???? Or was it some Ipod that you attached to the truck to get the digital information. The reason Im asking is because if I replace the defective part do I need this program or Ipod to reset everything so the new part will work, or will it automatically start working correctly after the good part is installed???
I'm using a Snap-on Verus Edge tablet but many scanners are available to read codes and data as well as perform bidirectional testing. You can get the system to relearn by disconnecting the battery for several minutes. When you restart the truck don't operate any heater controls for a couple minutes while it's relearning.
Just finished installing mine. Before you start, disconnect your negative cable. It will relearn automatically after reconnecting.
If we don’t have a computer to hook up to recalibrate it, will it still work like it’s supposed to? Or will I have to take it to the dealer?
Disconnect the battery for several minutes the reconnect it. Start the truck but don't touch the heater controls for a couple minutes. The system should perform a relearn on its own.
So if the driver side is pushing warm air and the passenger side is not, the actuator motor to be replaced is on the passenger side, and not the driver side? Is this correct, meaning it’s the opposite side ?
I would say if its the passenger side that is not responding then it's the passenger door actuator which would be the lower actuator under the heater case.
I have a 2014. It’s blowing cold on the passenger side, warm ok the driver side. I check the actuator temp door on the driver side and I can see it physically moving (opening and closing). So it appears that is not it. Have any other recommendations to check or other issues the system could be having?
@camerons3331 the left or driver blend door actuator is on top and the right actuator is on the bottom. Are you watching the correct one? Is it setting any codes? Try a relearn procedure. Could have a broken shaft on the door. On some vehicles when the heater core starts to plug up one side can be affected more than the other although I haven't had that issue on these trucks
@@PhillipBailey I did a reset where I pulled the fuses from the driver side panel and unplugged the negative battery terminal, reattached it and then put the fuses back and it seems to be working. I did check the actuator on the bottom is moving, did not know if it was moving prior to the reset though. But for now, there is cold air on the driver side. We will see how long it lasts
Once I did this my ac was working for about a day then starting blowing warm
What’s the part number that needs to be replaced
Part number at 10:30 in video. 22808876
Mine blows warm air on drivers side passenger side is cold ? Could this be the issue
Yes likely is but you need to scan it for codes
For the previous 3 month im having same issue warm driver side cold passenger
Today the car did the opposite cold driver side hot (not warm) passenger side what your suggestion 🤣
Since i had the same issue you explained in this video but recently by luck it fixed itself and reverse the problem to the passenger side does that means my issue is only for the the passenger side acctuter or just change them both to avoid it from happening again
You need to have the HVAC system scanned see what code/s it's setting.
@@PhillipBailey mines the same cold driver side passenger side not cold. No engine light on. What u think the problem is
@@pengzhu6572 you need to scan and test the HVAC system it's probably a failed actuator. Driver side or left is on top. Passenger side or right is on the bottom and I'm not sure what that is like to replace.
How can I find that exact part?
I'd recommend the dealer. Part number at 10:30 in video. Verify part number by vin
Hi that's exactly what my 2014 is doing blowing hot on driver side and cold on passenger side
Very common problem with all manufacturers today. just fixed a dodge yesterday and now a Ford today. Some are a nightmare to get at depending on which actuator it is and which manufacturer. Good luck.
Just went through this issue, got to it through the bottom cover. Didn't touch the glove boxes. Swapped it out but after messing with the temperature controls it's doing the same thing. From this video I'm guessing it needs to be calibrated..or maybe it went out again for some reason. Any thoughts?
@@damasofuentes5765 try to relearn the doors. If you dont have a capable scan tool try disconnecting the battery for 20mins. Reconnect and start the truck but dont touch the heater controls fora few minutes.
@@PhillipBailey thank you so much for the reply. I'll try that this weekend. You've gained a subscriber sir
@@damasofuentes5765 Evidently there are two separate actuators. The one that u accessed from underneath is for the passenger side. There is another on top that needs to be accessed by removing the glove boxes and some modules that is for the drivers side.
