Outstanding product and price
I was a little doubtful that the items I had ordered would solve the problems, I was having with my 1998 Cadillac deville. But, it turned out they were just what was needed. On the phone with one of 1A auto’s technician who assured me that I had the right parts for my car based on it’s identification. The prices were unbelievable compared to the dealers and other auto repair shops prices.

Part for a 1997 Deville
Thanks 1AAuto!! I thought I would have to find this part at a salvage yard. My luck, 1AAuto had it instantly! It was delivered in 5 days! And it was identical to the old part. Also came with video instructions on how to install myself. Great deal!!

Im a little confused on the actuators I want to b sure I purchase the right one.. Whats the diff between this actuator and the automatic one which is $141. Is the automatic with Cadillac that has the temp setting on the passenger door?
Mann X February 20, 2019
The item listed at $141 is a Genuine AC Delco unit whereas the one currently being referenced is our 1A Auto house brand. 1A Autos house brand parts are manufactured by various aftermarket companies specifically for us and built to your vehicles exact OEM specifications. They can both be used on models with the Automatic Temperature Control. The easiest way to tell if you have the Automatic Temperature Control feature is whether or not you have a digital display to adjust the temperature. Hope this helps you out!

I have a 99 Deville with the automatic climate control settings. The A/C blows hot out of the driver side and cold out of the passenger. I checked the refrigerant and it has the correct amount of pressure. I was wondering since there is a way to change the passenger temperature by a few degrees on the door panel if there are 2 different temperature blend door actuators, one for each side. Would I need to replace the actuator on the driver side? Or is there only the one actuator, the one shown in the video?
Seb K July 8, 2019
You only need to change the drivers side but you should change both because the other will go out soon.

Hey, I have a 99 eldorado and I think it’s similar. For my car, there is one blend door for each side. There’s one right behind the glove box that seems like it would be difficult to access that controls the passenger side, and the one right above the sound panel on the bottom controls the drivers side. I would disconnect that bottom ones metal arm from the actuator and move it back and forth with the AC running, and that’ll tell you if that’s the one at fault. Best of luck!

I had the same problem on my 1998 Eldorado and I didn’t know witch one to change so I did both. There is one behind the glove box and one below underneath the glove box
