Where I'm heading with this is my 2000 Accord has a button to turn ac on and off also it has a button for fresh and recycled air, which is very nice. I have full control over it. So I'm wondering if anyone put a button or a switch at least for ac, so when you have it on defrost in winter then ac compressor doesn't run and not only that heat is not the greatest like we all know it just would make sense to not have ac on. No I know when there is moisture ac helps defrost in that case you can always turn it on but for the most part I'd be leaving it off. 

And not sure on recycled/fresh air door if it could be put on a switch. I don't see why not for ether just haven't looked that hard in to it. 

Some day it will be like in a plane with all the switches and guages.

Thank you @IBMobile I just want a simple on/off for ac like my car has, I don't care at all how dodge made it. 

Just to clarify, this on/off switch for that green/white wire to make ground will turn compressor on/off and use all pressure switches like designed, right? I'm sorry I'm like @dripley electricly challenged when it comes to diagrams. It makes sense but want to be sure before I go cut things up. 

Blend door might just go on a choke cable

Yes the pressure switches are utilized.  If you look at the wire diagrams just above you'll see the light blue circled area is the same in both.  This is where the PCM and switches are joined to the AC dash controller at connector C-130 in the PDC.

 

I tried this on my truck.  I removed the HVAC controller to access the wires behind it and when I ground the light green/white wire the AC clutch is engaged all the time, in all vent positions, while the truck is running

Thanks, it is now on the list of to do. Appreciated your efforts. 

@IBMobile I just did the AC mod, is this the right wire I cut? I haven't started the truck yet, but tomorrow were going to Wisconsin dell's for a weekend and I may need it lol.

The green/white wire behind the AC controller.  Leave a little pig tail (2-3" long)  from the plug in case you want to use that function again.

Could you please take a second look into just added a picture. Thank you for your help.

So I spoke with @IBMobile on the phone last night and yes what I posted with pictures is how it's done. We drove about 180 ml this morning and it's working as it should. I can have a selector in any position and toggle a switch and it works 

So I'm happy and once again thanks to @IBMobile for figuring it out. 

It should come in handy in the winter. One thing should be done is to cycle ac every so often to keep things lubricated.

Just remember the compressor pulley bearing is a sealed bearing. It can fail regardless of compressor usage. In the dead of winter it can get so cold that the compressor will not start. Freon pressures will fall with extreme cold and the lo side switch will prevent it from starting. This is normal.
