Cadillac Seville / Cadillac Eldorado Forum Discussion, Air mix door/actuator's technical name in Past Cadillac Vehicle Discussion; send me some pics 2 email@example.com I need to make the same repair. 15-72654 - Air Inlet Valve Actuator
Oops, I just noticed that Bigrich and Pogo have Devilles. After looking at number 47 (GM# 89018381), I don't think they access thru the glovebox like on the Seville. Try the Deville forum for better luck with your questions.
There are left and right "temperature door" actuators and a "mode door" actuator that is in control of air distribution.
Locations vary by model and year.
There is also a "recirculation door".
GM doesn't use terms "blend" or "air mix".
At least not in the manual.
Pretty much all the doors "blend" and "mix air" so....
A question, as far as I look at the pictures and also the sockets in FSM, it seems that the both actuators that move "temperature door" and "mode door" are the same part? is this correct? I am asking this since I have IPM B1340 and IPM B1343 codes, the former is blend door, and the latter is inlet door fault. I am trying to buy the both, and looking into the online part listings, it seems that they have been listed as the same part!
On the 96 Eldorado's you can access the heat/cool blend door regulator thru the panel that easily opens in the back wall of the glove box and can be manually manipulated if needed.
You describe a zone problem & that door actuator is easily access after removal of the lower panel just above the pass. side foot area. If you manually move this linkage is will effectively combine the separate zones back to one zone and you are back in business.
To restore the separate zone function this door actuator will need to be replaced. You can live without separate zones when the part costs $185.00+labor
Some of them might be the same part number.
There are many factors, I usually give my parts guys the numbers off the old one so that he can be sure to get me the right part # for replacement.
Depending on the year/model they MIGHT be the same but usually on most newer cars they all vary.
The driver side air blend actuator is on the driver side, behind the carpeted panel on the side of the shifter console. There are two actuators in that area--the one towards the front of the car is for the driver, the one towards the rear is for the rear blower unit.
All good stuff here. I got a 2003 Seville SLS. I get nothing but heat from the driver side and I live in Texas. No bueno. Passenger side is good. I got a quote from a mechanic I always use, he says roughly 620 and a Cadillac dealership said 680. 5 and 4 hours labor respectively. I dont want to spend that kind of money. I figured i can try and take care of it myself. Can yallhelp me find the location of the actuator on my car? Thanks.
