I just unplug myne in the winter and plug it back in in the sumer i have done that with all of my 1989 F-250 7.3 because it did almost the same thing as it does in my ranger. but i noticed when i put it on one of the settings where the compresser is suppolsed to be on my moter acts funny. IE.the RPM's take longer to drop. will this mod stop that?

The mod switch in the OFF position should produce the same idle behavior as when the HVAC mode switch is in the OFF, VENT or FLOOR positions because it does the same thing. By interrupting the purple wire, you are telling the PCM not to command the compressor clutch or do any idle compensation for its load.

I am going to do this mainly because I was wondering why I was hearing my AC compressor kick on when I had the vent on the feet/head position.. I was so mad!...lol

I saw someone posted a youtube video and they had a switch that would indicate their AC on. How would one wire it with a simple toggle switch that has an LED in it: Such as this:



Since there are three plugs. The purple wire would be cut in half right? One would go to one terminal while the other clipped end would go to the other terminal. Then that leaves you with one left. Do you hook the 12v source say from the ciggy adapter to the last terminal so when you hit the switch on it would illuminate the led indicating that the switch is off, or vise versa...etc?

Thanks,
-Nigel

Welp I just did this. I should take a picture of what I did and update. But I pretty much used just s single small toggle switch. And drilled it into where the stock airbag key turn/off switch is on my 01.

Flick the switch and the compressor acts as normal flip it off and I can now have the feet/head air not kick on the AC... which drove me NUTS during the winter time.

Very happy I found this thread!
