Dorman 604-029 HVAC Blend Door Actuator Compatible with Select Models

If you have a loud clicking in your dash, it's likely the blend door actuator. This was a perfect replacement fit, and the part itself is easy to install, it's just a little tricky because of the way Jeep designed the access. It works just like it should and seems to be of good quality.

Installed today and corrected the problem. No more clicking and the part fit perfectly in my 2011 JK Jeep.

The blend door actuator in my 2013 JKU gave out in the most problematic spot, behind the glove box. Installing the part was tedious to say the least. It took me about 3.5 hours from start to finish with a lot of scrapes on both hands and arms, but worth it considering I saved hundreds of dollars doing it myself. A few things: I highly recommend using a ratcheting compact bit driver for the screw in the back. I bought a set here on Amazon for 5 bucks that worked perfectly for the 7mm bit needed for the screws that are located at the front and back. There are Youtube videos that recommend one but I noticed that none of them are ratcheting. A ratcheting one will go a long way. Trust me, your fingers will thank you! You also won’t be able to install the part unless the connecting port is “turned” in the right spot. The alignment tool included in the box is useful in this aspect. You just stick it in the port and turn until the door lifts. Then you will be able to mount the part flush to screw it back in. Also, I know there are some who had to calibrate after install but, at least for my JKU, I did not have to. The part worked perfectly fine. I immediately tested the cabin air system that usually triggered the click, click, click. Nothing. Drove it around for a few minutes and absolutely quiet. Feels like a brand new car.

I appreciate that Dorman makes products for cars. They're usually a lot more affordable than the ones branded by the car manufacturers (in this case Chrysler). Given that the original failed after only a couple of years, Chrysler is apparently not above using cheap, plastic gears in their products. I would expect this Dorman to last at least as long, and hopefully longer. In any case, it's less than $20 bucks, and I was able to install it myself. There were no surprises, and it fit as the original did. 9 month update: My wife says that it's making that clicking sound again. It's intermittent at this point. I'll have to pull it out and take a look and see if the plastic gears have broken. It would be difficult to say bad things about Dorman though. It's Chrysler's bad design. Edit: I removed the Dorman actuator and popped it open. I don't see any broken gears, so I'll add a star back for now. Another Edit: I've been using the 2nd one for about 6 months and I'm starting to hear odd noises from behind the glovebox. I'm worried that it's going to fail again. These things seem to have a lifespan of about 8 months, give or take. I'm wondering if whatever is controlling this thing doesn't realize that the door is already shut and keeps trying to force it more shut, and then eventually the actuator breaks.

Review: I recently replaced my vehicle's malfunctioning blend door actuator with the Dorman 604-029, and I couldn't be happier with the result. The installation was straightforward, and the actuator works perfectly, allowing me to control the temperature inside the cabin once again. It's a quality part that fits well with my vehicle model, and it’s been running smoothly without any issues. I highly recommend this product for anyone needing a reliable replacement part for their HVAC system. Great value for the price!

This part works perfectly in my 2011 jeep wrangler unlimited. The original part recently broke and I would hear a strange rattle in my car when I started my car and this replacement part fixed that. It took my about 30 minutes to install after watching a few videos but everything related to my HVAC works perfectly again now.

About one year later and it's broken. I am PISSED. Also, I don't recall seeing a video on here the last time I purchased. Dorman, if you knew you needed to include a tool to align the door on install, why not upload a video showing how to use that tool? And mentioning needing to reset the computer to get it to work? I should have taken all that as a sign to return it and get a different brand, vs wasting hours, frustration...and now I get to do it again. (The original part, as crappy as it was made out of plastic, at least lasted 10 years to begin with.)

The recirc motor in my kids 2016 jeep patriot was making all sorts of banging noises. Holy cr@p though this was a pain to replace! I'm very mechanical and have been working on vehicles for 25 years and this kind of stuff boggles my mind why an engineer would place them where they do. You will have to remove the glove box which is easy. Then remove the cover above the foot well, held in with 2 pop pins. You can reach in and unplug the motor from there easily. But then it will be a struggle with a right angle ratchet screwdriver to get the 2 silver screws out holding this in place. The lower one isn't bad but the top screw is done by feel, completely blind. And you'll have to be lying down across the drivers seat with your head down on the floor contorted and cursing to get to it. They are plain Phillips screws, not even the ones with an 7mm head on them for a socket, which would have made it much easier to remove without the tool slipping off. Make sure the one you remove is aligned properly, it should be in the recirc position when the vehicle is off. There is an alignment tool in the box you can put on a ratchet to move the door, but it's easier to just grab the white plastic end of the damper door by hand and move it if needed. Install is reverse of removal with slightly less cursing. No programming required, start the car and let it move through the recirc and fresh air positions, no more noise. It's worth noting there is a mode actuator and a temp actuator, both are this same part. One located on the drivers side of the center console by the pedals and one on the passenger side in same general area.

Fits well! Fast delivery

Le quedó bien a mi camioneta y funciona correctamente.

Bought this for a 2014 Dodge Journey. Easy to install with the right tools. Did the following to "calibrate" the actuator manually : 1) Connect the actuator to the power connector, and just let it hang loosely. Turn on the car. 2) Turn the heat all the way up on the climate control. This will trigger the actuator to go to "hot". 3) Manually figure out how the blend door arm needs to be do deliver hot air. 4) The climate control, the actuator and the air door are now set to "hot". Install the actuator to its place and tighten the 2 screws. 5) Play with the heat and verify the air is hotter or cooler. Turn the heat all the way down and verify the air is cool.

Quality product

Lo compre porque un engrane del mecanismo del actuador que abre y cierra la compuerta del A/C para regular la temperatura en un Jeep patriota 2013,la cual se encuentra debajo del tablero lado chofer. El repuesto funciona excelente, cabe aclarar que trae una hoja con los ajustes que deben realizarse con un escáner con módulos de A/C. Producto recomendable.
