1aauto: You may want to check the engine compartment for a broken or loose vacuum line, also check under the dash to see if anything's loose. Hope this helps you out. 1aauto.com 888-844-3393
Iya Honey: Hi I hope U can help with my prob. I have a 94 Cad Deville. Air would blow through the defrost no matter what you set it to. I thought I fixed that issue by replacing a motor in the ac programmer.@ Two weeks back, air blew through the vents but it would not get hot. As of today it blows back through the defrost & still does not blow hot.I would really love some heat, I almost don't care where it blows. Please and thank you.
Sorry 1 more Q the actuator U replaced I don't have. Is that possible?
1aauto: It might be,it could also be a bad relay, fan motor or resistor. 1aauto.com 888-844-3393
Keke Brown: I have a 1996 cadilliac deville and the fan comes on when turned on but goes off then back on every few seconds could this be my control switch?
1aauto: You may want to test the switch and the blower motor with a test light or an ohm meter to see if there's power going to them. Hope this helps you out. 1aauto.com 888-844-3393

monsterlokote: i have a 02 deville the ac only blows cold air on one side what could it be?
1aauto: The actuator is located in the same spot at this but the part might be slight different that the one shown.
melody oliva: i have a 2000 cadillac seville sls is the actuator in the same location?
driver side is blowing hot air and passenger cold air.
1aauto: The issue is most likely going to be related to the actuator as shown in the video.
mark smith: i have a 96 sedan deville that always blows hot air. I took it to get charged and they said it was full and suggested i change the fuse. I did this and it still blows hot air. what do you recomend?
SouthernBoyProud: This is different from my 96 deville . I took bottom off mine like in video and no actuator so I think it's on top...
rcmjr94: I was told to replace this by a mechanic because the ac does not blow out of vents on dash only the floor and defroster so I did but still does not work what can I do next?
1aauto: you will want to see if the actuator is bad for the blend door or if the physical door is broken inside the HVAC housing.
Donald Perrell: My 97 Deville blows hot on passenger side and cold on drivers side. Is this the actuator I need to replace? I will buy from you if it is. Thanks.
Steve Dzubryk: I have a 98 deville and my a/c isn't charged and my heat doesn't work and it doesn't even blow air out of the vents if its set over 70
1aauto: it should be located in the door under the door lock, if it's the door lock actuator that you are referring to.
1aauto: We currently do not have an auto repair video that shows that particular repair.

redbaron2448: DOES ANYONE HAVE A VIDEO FOR A 1999 CADILLAC SLS (AC ACTUATOR HOW TO REPLACE IT, OR EVEN SHOW WHERE ITS LOCATED. THANKS
1aauto: This video shows you how to fix the blending actuator if the vehicle constantly blows hot or cold air. It sounds like a different actuator may be acting up. We currently do not have a video that shows you how to remove the other one that could be causing an issue.
redbaron2448: Great Video Thanks, Question, which one was that for, The Driverside or the passengerside. Im getting COLD air on my pass side and HOT air on the drivers side vents. Thanks
