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.

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.

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!

Appears to be good quality, only time will tell. Exact fit. 15 minutes install with no recalibration required

My 17 JKUR suddenly had cold AC only. I figured it was this, and it was. The install of the part is not terrible, as long as you can get the air duct out of the way. Mine was a bit tough to break loose, but once out made things much easier. I also removed the one metal support bar under the steering wheel closest to the duct and also the little fan that's the air cabin temp sensor. I have large hands and this allowed me to more easily work through the hole available. It also let me more easily get my extensions and socket in to remove the bolts holding the mounting plate you have to remove. Before you button everything up test the unit and make sure the arm is clocked correctly, giving you the entire range of temps. Without the duct in the way you can easily see the arm moving and make sure it goes across the range. I had to move the arm a notch over to get it correct. My buddy didn't do this and now only has hot hot or cold cold, no in-between. Another note, I have a little electric screwdriver and it made the project so much easier at the actuator. You don't have much room so not having to turn a screwdriver was a huge plus.

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

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.)

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.

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.
