In this video I show how to replace an HVAC programmer that’s gone bad in my 1989 Cadillac Seville. This is the same procedure in cars 1986 to 1991. This basically is a blend door actuator but it just has more complexity as it uses electricity and vacuum actuation to control it.

I have a 94 DeVille and I've been trying to get my programmer out for months ! I've searched the internet for a while. I didn't think your video would help me because your Cadillac is older then mine and I was pleasantly surprised that it was pretty much all the same except the location of the glove box. Your video saved me ! Thank you for going into such detail and explaining step-by-step what you did. You're awesome.
Excellent video. I could still follow along even though it was a bit shaky. I need to do this on my 88 Eldorado. The guy I bought it from had someone install a new heater control valve and thinks they missed hooking up a vacuum line. Now I know how to do this job! Thank you so much and happy Valentine's Day 2023!!!!!!!!!
You did a wonderful job!
I have a 1991, thank you so much. One side is blowing cold, the other hot when it's on 90 heat. And it's only blowing defroster. Going to give this a try
i have a 87 seville and these videos are helping a lot thank you
I have a 1986. Yours must be a 1987 or 88? Bc the 4.5. I have a 4100. I really need pics of your wiring fuse boxes and so much more.
I have close to the same model. How do I remove the ecm? I've unplugged mine to a new one but can't get the old one out
What is the name of the part n part number I can not find it for my 91 Seville
