hey bro since you know electrical is there anyway you can find out for
us if you can add a shock sensor to our fits. some say it's possible
some say not.
i believe there is a thread or two on this. but i can't find it right now.
but if you can find out and let us know that would be great.
thanks
Nick

Good question!!!! I've been wanting to add a shock sensor as well. We never got an answer in the old thread, which I had to find...

And i am deploying, so it will be a while. But the post you linked to basically describes how to do it, a shock sensor connected to the door input should do the same thing.

I'm not sure Dave?
Maybe Roger's Fit will let us know.
but i'm thinking he will need the whole alarm system
schematic to start.
Roger's Fit please let Dave know and he will provide
you with schematics of what you need..
Man i really want to do this to my car.
if this doesn't work then i will be installing
my compustar system.

Just a reminder... it is not a good idea to let the AC system in your car sit unused for long periods. The refrigerant inside helps circulate the oil when the system in on and helps lubricate internal components. If unused for long periods, the seals dry up and you can get leaks in the system.

I know an even easier way.
1. Turn key to "on" (position before crank).
2. Move fan knob to "off".
3. Temp knob full blue (all the way to the left).
4. Position knob full left (arrow pointing to face only.
5. Turn key off.
6. Press the AC button and hold it down.
7. Turn key back to the "on" position and wait for 7 seconds while still holding the AC button down.
8. Release AC button and start the car.
Voila, now the AC doesn't come on automatically in defrost mode! You can however, turn it on if you're so inclined.

just remove the switch behind the panel- only takes a few minutes to do!

B. On vehicles it does work on, you only have to do it once to "program" the HVAC unit.

If disabling the AC from defrost floats it, rock it. But even the few minutes it takes disabling it is a waste to me. I turn it on to clear the windshield and it does it's job. Why screw with changing it? To save GAS? Please, it's a momentary function. Your foot will surely do more damage to that end than the AC running while you defrost your windshield.
Is that a good enough reason?

Well, I haven't had the AC on since October. I won't run it again until approx June. That's eight months of it sitting idle a year. If it's true that over time non-useage will create problems, I can't imagine a more perfect storm than that.

The real point is that I have control of when the AC is used with the defroster or not.
Btw. I'll probably leave the selector in the heat/defrost position all winter long and only hit the AC button when dampness causes fogging issues.

In my case, it's to save power. There is a noticable difference in acceleration if the compressor is on .vs off.
Like Virtual, it also annoys me that they take away the option of deciding how you'd like it to behave. While the AC reducing humidity does clear the windows faster, it's not always necessary. If the window has been warmed sufficiently by the heat, you won't get condensation anyway.
In winter months, I'd be inclined to run the AC briefly for the initial clearing of the "heavy breathing" when you get in the car, then use conventional heating through the defrost vents to keep it that way. Running AC will remove some heat from the vehicle while defrosting since that is its very nature. On cold days when you've just started the car, I'd prefer to keep as much heat in the car as possible. After the car has warmed up, the heating loop can obviously overpower the AC's cooling, but that first five minues or so...
