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.

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.

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.

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 is an exact duplicate of OEM part. Not very difficult to install, but some mechanical capabilities are required. In order to use it, it needs to be calibrated by a mechanic with a computer screen device.

A bit of a challenge to install because of clearance getting to it, but little mechanical skill actually needed. Worked perfectly in a 2017 JK…

Worked for less than 2 years and roughly 2000 miles. Bought it in December 2023 and it stopped working in October 2025. Considering what a pain it is to replace, I would hope that it would last much longer. There are other reviews saying the same thing. Won't be buying another Dorman. That's for sure.

Took about an hour to get this installed on my 2011 Wrangler JK Sahara. Of course it was the worst one behind the glove box. I watched a YouTube video and went after it. Worked perfectly once I got it in. I 1000% advise getting a 1/4” thumb ratchet drive if you are replacing this on a JK as well. Great part so far. I’m gonna hope it lasts!

Installed and works perfectly.

Fits well! Fast delivery

Le quedó bien a mi camioneta y funciona correctamente.

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.
