Default Airmix actuator?

Ok my wifes olds ECC is flashing and blowing cool air instead of hot, She has the passenger side heat control and on that side of the car the air is frigid and I had to close the vents.

might this be the airmix actuator or is there a second one for the cars that have the pass side control? Also I'm aware of the redneck fix so theres no need to post the link, but where is the actual actuator? Its hard to tell from the redneck fix thread pics on what exactly I'll need to remove to turn the heat back on! <brrrrr>

Ok, I've had a thought <gasp> if the airmix defaults to full heat if the rod is disconnected, all I need to do is pop the rod off until spring rolls aound. Right?

Popa, did you read this? This may be the most definitive info on the subject located in one place.

Yes , I have read and printed that out.

What I don't know is if the cars equipped with the passenger side control are different.

My wifes car has the passenger side control and on that side of the car the air is very cold (straight from outside would be my guess) regardless if its on, off, hot, or cold. On the drivers side it gets to luke warm when the ECC is set to 90.(makes for long defrost times these past few sub-zero mornings).

I'll be checking the airmix actuator tomorrow but I think I'm dealing with more than one problem; so any ideas, drawing, descriptions, etc. on the pass control system are welcome.

The procedure to replace the airmix actuator in an (1991-1996) Olds 98 and some 88* are as follows

1: empty the glovebove
2: Remove glovebox by removing the 4 screws securing glovebox to the dash frame at the bottom of the glovebox. They are either 5.5mm or Phillips head screws.
3: Remove the module above the airmix actuator by removing the one 6mm screw, slide it towards you and position out of the way to the right. Theres no need to disconnect the wires.
(This will give you enough room to get a small 1/4" ratchet onto the Airmix Actuator screws without much problems.)
4: pop the airlix lever off at the threaded end of the rod.
5: remove the two 5.5mm screws. The second one is on the far side of the actuator almost directly across from the one you can see. Feel along the rear side until you find the circular recessed area; the screw will be in there.
6: Disconnect the electrical connector.

Installation is the opposite of removal. Be sure to calibrate before connecting the threaded rod.

This is a very simple part to change out. I pulled and disassembled 3 at the yard in under an half hour before I found one with a good gear.

New part#'* - ECC - 16141822
................ non-ECC - 16124942


* I got my junkyard part from a 1998 Olds 88 and it was setup exactly the same as our 96' 98. I do not know which years of the 88 would be the same.

Maybe this will help someone sometime.
