  • Controling AC/Heater controls VIA CarPC

    Im not sure where to post here goes...

    My idea is to use a meter to get the different voltage ranges that the controls for the AC/Heater and then duplicate those using software on a computer and possibly output them through LTP/Serial ports into a custom made plug for the controls. I have a Scion xB and the controls get on my nerves, i could put something else there if it wasn't for them. and i figured since i had a carpc, why not try to control the functions with that.

    It doesn't seem like its a hard not sure how to begin though.

    If you had a temperature probe to ....lets say...your headliner you can wire that to the computer as well and have a digital thermostat keeping the temperate at...lets say....a set 73 degrees, where the heater/airconditioner will kick on when the temperature changes....any input/comments/hate would be apperciated. Thanks.

    I wouldn't have a clue how to do do you like the xB? I love those! Everyone I talk to think they are ugly, I think they rock. Are they as gutless as I've heard?

        I'm pretty sure that the A/C controls are digital, so you can't just send a different voltage and get an effect.

        Also, you got a lawnmower engine

            check the irc chat, a guy on there had his working, was thinking of selling a unit that would do this.
