A/C "button" modification?

It's beyond me why there is not a separate button to control the air condition, but as we all know, there's not. Today I was thinking about some way to add a button allowing me to turn off/on the A/C when I wanted, and not have it be dependant on which vent control I selected. I was wondering if anyone had done this, or has any ideas or links?

Look at you steering wheel does it have J E E P written on it? That would be the problem

My old Dodge Raider had the A/C switch that could be used in any hvac position. It IS the best system, but at least the Jeep does have strong air and heat. The Raider was in trouble below 10 degrees.
I'm guessing you could adapt hvac controls from some ricer (the Japanese stuff usually uses a compressor switch).
IMHO, it sounds like TOO MUCH P***ING AROUND.

its not that big of a deal to put in a switch. it would consist of a switch a diode, relay,some wire. if you can get a hold of the service manual for your year jeep and email me a pic of the wiring diagram that has the ac compressor and blower motor i will make you nice clear step by step instructions on what to do. when you press the button your ac would turn on and no matter what position your vents were at. if you want a little more control i could add a three position rocker and resistors to get different blower speeds. with that one you would have seperate ac and seperate heat controls.

The way I look at it, we are all lucky we even have a/c and heating in a jeep

I'd like to have the option to disable the compressor on mine, too. It really irritates me that if I want air coming our on the floor and the windshield(or the floor and dash vents) the stupid compressor has to run. The extra oxygenates that are added to fuel in the wintertime already hurt fuel efficiency, and then I have to deal with the added drag of the compressor, too.
It can't be that complex to wire in a button. I really need to get off my lazy rear and take a look at the wiring. Oh, and I need a new multimeter, too.

Okay... so does anyone have the schematic? I would think it could be as easy as finding which wires on the back of the vent selector trigger the compressor to start. Bypass those with a separate switch, and done. Just had another thought... what about switch enabling the fuse for the compressor circuit? Is the compressor on it's own fuse/circuit (too lazy to look at the moment)?

All- If you do figure a way to control the compressor, don't forget to turn it ON from time to time over the winter; saves the seals.
BTW, Prfct, I don't think the compressor cycles much if the heater temp is turned up, and the outside temp is low.
At least the six can handle it; my old Scirocco with air felt like someone pulled a plug lead off when the compressor ran. I always turned off the air before I passed someone on a two lane.
