This was on the passenger side under the glove box and it works the heater on the driver side. Great product and super good price

Fit perfect, works perfect!Put a few used ones in but all broke ( plastic gears inside)This unit is supposed to be made beefier.Time will tell. So far very happy!!!

Worked great in my 2004 GMC Sierra 2500 Denali 4X4. Fixed the issue of heat blowing on the passenger side (hot air only). Amazon offered a better value than buying it from other places.The job was abit of a pain to do, but that has nothing to do with the product. I followed these instructions from Instructables.com (How to remove drivers side passenger side temp contr).[...]

This part was exactly as described. I had to do some research and make some phone calls but this fixed my problem. Heres my experiance with my particular application in hopes that it will help someone else. I have a 2005 Chevy Silverado with auto air. My air inlet door actuator had failed. To be clear this is the door that lets outside air in with the A/C on and then closes the door to block off outside air when in "recirculation" mode. This allows the A/C to recirculate or "re-use" the already cooler and dryer air inside your vehicle. I had read post after post about how you had to take your entire dash out to access this thing, which is on the passenger side and buried almost all the way to the fire wall. I wasnt looking forward to it. Once I began work and had a lot of the dash parts off and dash cover off realized just how bad it was going to be until I remembered reading, on an Amazon review of same part, where some guy cut his A/C duct out of the way and I thought he was crazy! Turns out hes not! It was either cut duct out of way or really have to take entire dash out, braces and all. I was fortunate enought to have an air saw that made quick work out of the duct. This doesnt sound as bad as you may tthink. I made one straigt cut just to the left of where the actuator was located, drilled out the plastic weld where it attached to the de-frost duct and the other end slides right out of the flex duct! Done! I then removed the silver control module located just below and in front of this piece of ducting, just be sure to unplug all the connectors on the bottom of it (I believe it has something to do with the onstar or XM system.) Now to re-install the duct I slipped the lose end back into the flex duct, realigned the end I cut, and used aluminum duct repair tape to reseal the cut and re-attach it to the system. This is the "chrome" like tape you can find at Lowes or even some auto parts stores that is often used to install or repair home A/C duct work or even make a hasty auto patch repair with. I then used a zip tie to re attach the duct to the de-frost vent so it wouldnt rattle around once the dash caover was back on. Re assemble dash and your done! You can use a plastic glue if you want but i didnt want a harsh odor blowing out when the dash heated up during the day so I used the tape. Im sure you could use regular duct tape but the aluminum stuff has more insulating properties to it. This method created so much space to access the actuator with a fraction of the work or time it would have otherwise. Just be sure to plug in the actuator before re applying power to vhehicle. The truck will automatically learn the position of new actuator and adjust as necessary. The new one works great and my A/C will freeze you out now!

I usually try and stick with OEM parts however after doing a thorough search the OEM was very expensive. I did not want lower end substitutes but the Dorman is pretty well constructed. It took a bit of time to remove the old unit. After some jockeying around the replacement went in. Remember to allow the unit and the system to reset. Usually it is best to remove the fuse before doing the install. After cranking the engine let thing run for a couple of minutes to allow the blend door to adjust. If you start playing with the controls it could throw it off. It happened to me so refer to many YouTubes out there that outline removal,install and reset procedures.
