1994 Buick LeSabre Blend Door Actuator location and removal

[Tinkerin_wit_tools]

Have looked online and have tried to do my own searches, but with mixed results. Just wanted to know where my blend door actuator/s are located and what I need to remove in order to get to it/them. Any photos or videos would be preferable. Never have removed any of the dash before, so this is a little intimidating to me. Engine compartment repairs have done, but never this. Can anyone help? All are appreciated. BTW, all of my research has brought me to this one part and even troubleshooting with those at the parts store. Just a nagging issue, but not a necessity...yet!

Exactly what is your problem?

A '94 is vacuum leak prone.....doesit have the a/c controller- as in climate control? with all the pretty vacuum hoses emitting from it? That tend to leak at manifold connection?

There used to be a vacuum leak near the firewall, and I fixed that last year when it wasn't blowing at all. During any kind of acceleration, the air doesn't blow as strong, almost like it is using some of the vacuum in the system. I was told that the actuators fail constantly due to the cheap plastic parts. Just want to know where to find them/get to them for removal.

Remove the hush panel under the dash on the passenger side, and remove the glove box(some models have tabs at the top rear of the box, and you move then to drop down the box fully....then you will see the heart of the control system where the glove box was...

actuators are the last things to look at- you have an unhood vacuum leak- most likely- check all hoses, check valves and vacuum lines for leaks, cracks and function.

This weekend, I was going to replace all the vacuum lines as a precautionary measure anyway. As far as check valves, what are they and how many would be attached to the lines? (Sorry for the dumb question, but this is the first time I am starting to really get into the repair and function of the a/c system.)
