Thanks, will do.

Pulled the actuator out today.



Took hold of the arm and it moved without much trouble...gears inside didn't move with it though...so I guess that pretty much confirms the actuator is shot.

I'll see about ordering a new one soon.

Will definitely do that, as I just now popped the thing open for final confirmation before I go spend the money.



Look at that Grand Canyon

Searching for part now.

Quite welcome.

Got the new one in today. Here'* a little guide for installation and calibration, more help for LeSabres in installation but the calibration will help everyone.

New actuator, make sure you have the arm from the old actuator:



Even though it'* a lot easier to install these in LeSabres, it'* still hard to get to that rear bolt. Take precautions to make sure you don't drop the bolt or your tools back there...I did it more than once while removing it. I tied fishing line around the bolt and the socket to keep from losing them.



Attach the front bolt and the electrical connector first, they're easy to get to and will make it easier to attach the rear bolt. After that, the rear bolt will take time...try to tighten it down there by hand at first, then turn it with the socket, and when you have enough clearance, the ratchet can be used to tighten it the rest of the way. Cut the lines off the bolt (if you did that) once it'* tight.

After it'* in, it'* time for calibration. Start by turning the temp to the maximum heat setting.



Wait until the actuator arm moves all the way to the right. Move the airmix door all the way to the right, hold it there, and then snap down the metal connecting rod to connect the actuator arm and airmix door arm.



Next turn the temperature to the maximum cool setting.



Watch the action of the actuator arm, connecting rod, and airmix door arm as a whole for smooth, quiet motion throughout the full range. Verify that the airmix door moves all the way to the left.



Then set your temperature to the desired setting. Turn off the ignition and restart the car. Either let it idle for a few minutes or take it for a test drive to verify that the ECC has stopped blinking. If it has, then you are set to enjoy air at the correct temperature again!

Nice work. Nice pix. And, although they are not as sporty, there are a lot of things to really like about LeSabres.

The Bonneville is a wee bit more difficult to deal with on the airmix actuator. You're very lucky on that location.

We'll see how long it takes for someone to break my very relaxed 20-minute fix (must have witnesses)

(going for 15 minutes the next time one fails out west)
