Temporary AC disable?

Because you guys are my go-to source for arcane knowledge...

When I bypassed the heater core in my ZJ Jeep, I didn't take into account for the fact that this also results in one AC temp - frostbite. This is an issue since the ZJ (like a lot of cars) automatically kicks in the AC when run on defrost. Now when my windshield fogs up I go very quickly from "got rid of fog inside" to "caused condensation on outside."  Also, when you switch back to dash vents it leaves the AC on. SO morning drives are a constant dance of  run defrost until windshield frosts over outside, switch to dash vents, turn off AC, freeze until vent  air warms up to ambient, then start over because the windshield is now fogging inside.

Anyway, is there a safe way to disable the AC in the morning that I can re-enable for the afternoon? I'm thinking about disconnecting the ground on the AC clutch or pulling a fuse or relay or something....

I know I need to just do the heater core, but this freakish weather can't last much longer, and then it'll be all-ac-all-the-time.

Splice a switch into the compressor clutch wiring?

Put a relay in-line with the AC clutch ground and use a separate wire from the AC button to throw the relay, or add a second button.  

to be clear I'm not even looking to actually switch it inside. I just want to identify the safest place to disable it under the hood!

Just pull the plug on the driver's side of the A/C compressor.  That'll kill power and ground to the compressor clutch.  

I was also going to say wire a switch into the compressor clutch circuit. You could run into the cabin and control it from the driver seat. Or if you don't mind opening the hood every time I would just unplug either the clutch, or the high or low side pressure switch in the system. Whichever one is easiest to get to, all of them should disable the compressor if disconnected.

If you do unplug the compressor clutch make sure the connector won't touch the pulley, it's usually right next to it.

In reply to gearheadmb :

The wires come up from behind the compressor, and IIRC from my ZJ, they're not quite long enough to let the connector hit the pulley (the connector is mounted back a few inches on the side of the compressor body)
