Hey all, hopefully someone can help

my sisters 97 LeSabre which i drive from time to time is not blowing hot air inside the car on the passanger side

We have the electronic thermostat with the passanger climate control pad on the door.

The drivers side blows out heat at the correct temp
What'* exactly happening, if the fans are on, no matter what speed or level air flow (mid level, floor) the passanger side, its ICE COLD and at Full blast all the time, even when i shut off the entire system. Air still blows in. The only time the passanger air becomes remotely warm is if i lean over and press the control on the door to warm.
This morning was a very chilly ride by the way. lol 17 degrees..not fun :(

Also from time to time u hear this squeak sound that sounds like plastic rubbing under the dash, probably the blower fan im guessing. Its almost spring, ill deal with it next winter but has Anyone experienced this or know of similar issues??

Airmix actuator... I bet the climate control flashes for a little while too.

On my wifes 96 Olds 98 Regency Elite you can see it if you open the glove box all the way, pop the two rubber tabs over so it opens up even more and then you'll see it in the back and up a little bit. Its the black module with the white arm that has the metal rod attached at the end.

A quickie fix, once the car has warmed up, is to disconnect the metal rod off the white plastic arm and then move the rod in or out until you have full heat.

Fairly easy to swap out the module too. There are only two screws if I remember right but one is on the firewall side of the module and you'll be doing that one by feel and you'll need something like a small rachet to even reach back there. There is not alot of clearance above the module.

PM me if you need pics.

Sorry for the delay

Open the glovebox and empty it.


Lift up the glovebox a little with your knee and reach in with both hands and pull the rubber tabs (arrowed) toward you. I find its easiest to use one finger on each side and from the right side of the tab. This will allow the glovebox to open all the way

Once you have the glovebox open, the Airmix actuator is right there; unlike the Bonnevilles.




A quickie temporary fix is simply remove the actuator from the valve. its best to have the car already warmed up
mark where on (the threaded end of) the rod the white plastic retainer sits.
using needle nose pliers or something - Pop the plastic retainer up and out of the lever, rod and all.
swing the rod out so its pointing at you
rotate the head of the rod clockwise - off the airmix actuator arm and save the pieces for when you replace the actuator.
start the car and Adjust the metal valve lever that the white retainer was in so that it blows heat. (not the plastic one on the airmix actuator)
close up glovebox, just close it, the rubber tabs will fall slip back to where they should be without doing anything.


to replace the Airmix actuator, you might first want to remove the glovebox. there are 5 or 6 screws to remove a trim piece along the bottom (5.5mm?)
and then 4 screws at the glovebox hinge to take out. (5.5mm?)
disconnect the electrical connector on the right side.
undo the front bolt (4.5mm i think only 50% sure its been a few years now)
There is another one on the back, engine side of the module. You will need a thin socket/wrench to get that one out and you will be working by feel. Once you get the hang of it, its not bad. I pulled 5 or 6 of these out at the junkyard before I found a good one, all in under an hour. (from a 99 88 so I know its the same setup) and I didn't take off the glovebox and I'm a big guy.
Installation should be self evident.

Sweet, I'm gonna go buy me a Buick!

Riviera'* are also very easy to access. At least the passenger side.
