I'm not sure it is CRD specific, but since I have a CRD, I'll try posting here first.

I'm a little annoyed about the recirculation on the AC only going to the middle level vents, and not being able to use recirculation for both low (foot) and middle level vents.

Is it possible to put in a push-button type switch and plumb it in to the vacume line to the recirculation setting so that one could simply push this button for reciriculation instead of having to just use the single setting supplied by Jeep? My GMC truck has this button, and I really like this feature because it allows you to select what setting of ventilation and/or if it should be recirculated.

Anyone know where to source such a switch?
