Default Turning off the AC

Has anyone worked out how to disable the AC when you have the air select knob pointing to de-mist/feet or de-mist only? I have noticed that the AC is enabled in these two positions even if the AC switch is not pressed.

2003 - WRX Wagon

Cheers

Yes, this is a relatively easy mod as long as you are comfortable taking apart the area housing the stereo and the HVAC controls.

-Remove the trim ring around the stereo and HVAC controls
-Remove the stereo (4 screws)
-Remove screws holding HVAC controls in

With the HVAC controls free, tilt the unit so you can see the underside. On the right side on the bottom of the unit, behind the selector controlling the position of the air there is two small purple wires and a switch mechanism. cut one of these wires and you are good to go. Alternately I have heard of people taking the switch mechanism apart that gets tripped when you turn the selector to the defrost positions. With the mechanism apart you turn it around and reassemble it so that even though the mechanism is working it doesn't trip the switch.

Either method will work, one is just much easier to do. I chose to cut a wire. It's easy enought to splice it back together if I ever feel I need to.

Thanks to all who replied. I'll be doing this mod as soon as I get a free moment.

Interesting to me the number of people in the Portland Metro area interested in doing this mod. Must be something to do with the constant dampness we have, even when it's sunny.

Yeh Portland!

Yes it does turn on the AC, just not the light. For proof you can turn the heat to cool, and then switch to defrost, you'll feel the AC come on. Or open the hood and you'll hear the fans and the compressor cut in.

Yeh Portland!
Maybe it has to do with the fact that in Portland we are just cool enough to need defrosters, and unlike the really cold places we don't need them often. And that we have enough moisture that using them wrong causes the windows to fog really quickly.

I did this. It's been a while, but I don't remember moving any of the HVAC stuff... once the radio's out, you're looking at the guts of the HVAC system, and it's easy to see the mechanism that triggers the AC and the infamous purple wires.
The only hard part is working up the courage to REALLY yank on the trim ring to get it out of the dash. If you look in the FSM, it shows where the clips are, and it comes out a lot easier if you're yanking (with spring hooks or whatever) where the clips are.

Good luck,

Ben
