Climate Control Mod Help

I remember a long time ago running across a mod that let the driver control when the AC compressor turned on, a.k.a. you put a switch in to kill the power to the compressor when you were using defrost, anyone have a link?
thanks

A/C makes the defrost more effective (by dehumidifying the air). Are you trying to hypermile like some here are trying to do?

Just unplug the wiring harness at the compressor. Without 12volts to the magnet, the clutch won't engage,

I feel thats not a very good idea at all! (1) mentioned above your defrost will not work as well as it should.(2) without your compressor" pump" never spinning things are going to start drying up,[ie] the vanes in the pump,o-rings,ect. If you're looking to improve fuel consumption look in to removing the mechanical fan with another electric....a popular/cheap swap is the from a Ford Taurus. Just a suggestion

What about putting a switch into the low pressure switch circuit? I think that would work, and it seems to be a low current circuit.

Or, just realize that any time you are accelerating, you are sucking gas...

Ya I'm gonna do the electric fan swap, the vacuum gauge is a good idea too. I'm gonna wait on the AC idea.
Thanks guys! Rock on!
