I thank you for this video, I watched several videos on this subject, yours was the one that I kept going back to. My local Chevrolet dealership charged me $135.00 to check out the problem with my 2003 Chevy Trailblazer, the estimate to replace both the Defrost Actuator and Mode Actuator was $1,080.46. I was able to complete the installation my self for $146.00 buying my Actuators from the NAPA store here. I can't say it was easy for me, since I am 75 years old, but it gave me a great feeling saving the money and learning, I ain't to 0ld to learn.

How did you line up the mode door actuator with the flap door gear? My 2007 Trailblazer shop manual says to center the flap door and center the actuator. The problem is the mode flap door seems to be spring loaded into the closed position. There is no way I can hold the mode flap door in the centered position and install the actuator with one hand. Thank you for any information you may have for installing the mode flap door actuator.

Hi! Your videos are really helpful. Thank you so much for sharing your knowledge. I have a 2004 Buick Rainier.

Good afternoon. My husband and I have a 2003 GMC Envoy XL which we put our truck in the shop to fix the driver side of the truck because no hot air was blowing out only cold. Once we put the truck into the shop we received the truck back with the driver side working but now the passenger side doesn't blow hot air. In Sutton to the back send to either not work or blowing very low. My husband and I are going to try the methods mentioned in this video and let you know if it works. However, we do not hear any clicking noise. I will post another comment to let you know the results. Thank you for sharing. 😊 I do have a question about a noise coming from under the hood either when you start the truck or when the truck is in park. It used to be quiet once in neutral but at times it starts to be noticeable. Are you familiar with this issue and have a solution or video to show the problem and how to repair?

I own a 2004 Envoy XL. The blower vents all function except the one which blows into your face. I went to the back seat & was unable to lift the seat to expose the fuse panel as shown in this video. I did find a fuse panel just under the hood behind the battery. There was nothing in the fuse map as described in the video. So in the attempt to cause the AC control system to recalibrate, I disconnected the positive side of the battery for 10 seconds then reconnected the battery. I turned the ignition key on as shown in TV he video to recalibrate the AC actuators. I still have the same problem.

There's a failure in one of your actuators. The XL envoy is a longer wheelbase so the seats and fuse boxes are probably different. They usually have rear AC too.

OK so my 2003 Envoy XL SLE Kept defaulting to defrost ducts. When I got in there and looked at the actuator, there were 2, 1 closer to engine, the other closer to center consol. For me it was the second one closer to consol that kept flipping back to defrost ducts. I removed it and manual flipped the doors to dash panel ducts. To my surprise everything works as it should. Switch knob to defrost ducts and it sends the air that way, switch back to front panel that works to. Rear hvac control.. all seem to work as they should....WTF that second actuator is doing is beyond me. My only concern was that the control doors might flip back to the defrost send without the actuator in place to hold it. I decided to take the actuator apart manual turn it so the gear lined up to hold it in the front panel position, I re installed it and did not plug the power in to it....all is working fine

I know this is an old video but I have a 2005 GMC Envoy XUV and the heat doesn't blow out the front vents now but it does out of the back vents located behind the arm rest and center console. So Im guessing that the heater core is ok since it blows hot in the back and it's not the blower motor since its working back there so it must be the actuators in the dashboard? Im just trying to narrow down the issue before I take it to the shop. Any ideas or help would be greatly appreciated. Thanks.
@pfun413 жыл бұрын
I believe there is a separate blower control for the rear which means there's a separate blower for rear heat. If the blower doesn't work at all in the front it's likely a blower issue, if it works but not on heat it's likely a blend door.

I'm having a friend install it right now And now that it's installed the drivers side is blowing hot out the dash and cold on passenger Is there another actuator just for the drivers side? Or does it just need calibrated?

@@LailonaS Driver and passenger have separate blend actuators but it will need the new one recalibrated.

@@pfun41 Excuse my ignorance as I am trying to understand how this all works But he said the new actuator is working He replaced mode door actuator and said the blend ones are working So he thinks it's a recalibration issue And pulled 3 AC fuses and put back and it blows cold at first but then goes to heat on drivers side

When the HVAC in my 2005 GMC Envoy is turned off is when it makes the clicking noise. Is this the actuator? Or something different?
@pfun417 жыл бұрын
Pull the kick panels and track down the noise, only way to know for sure. But the HVAC doesn't receive power with the key off IIRC.

I know what your saying. When you turn off the blower it makes that clicking noise,mines does too,but it only clicks on defrost,and when I power off the unit,I have to keep it on face,or feet all the time so it won't click,I purchased the AC delco unit a while ago,I just picked a stubby 1/4 ratchet up so I can get back there with that 5.5 socket! I tried before,but if you don't have a 1/4 short ratchet,just go grab one before you bend over!I left it alone for months but I'm gonna do it tomorrow I needed that ratchet!I just watched the video again for reaaurance!Thanks again pfun41 !
