    air conditioning

    i hope this is the apropriate area.

    My car's air conditioning does not work it never did work too good, is there a way to upgrade it and to make it more worth my money? because after all it takes alot of hours to break into the dash and find out what exactly is wrong with it.

    You could always replace the blower speed resistors with a power transistor, connect the actuators to a fusion brain, hook up some new (or existing, depending on what you're starting with) sensors, and then interface it with a computer I think that would be worth the money.

    sounds complex. Im not very computer-savvy when it comes to wiring or anything. I have yet to do my first build.

    I was infact thinking about a way to control my AC through my PC How could i do that?

    No, it's not in the right forum.
    Moved to Off Topic.

    If you don't know what you're doing, then take it to a professional.
    Have you looked in the FAQ yet?
    How about the Wiki?

    does it blow and just not get cold? if so all you need is a recharge. You can buy a kit at just about any auto parts store and do it yourself. As for hooking it up to your computer, you are better off asking h3rk, he obviously know what he is taking about.

    I agree with darque about AC not being the best Do it Yourself job to tackle, an AC system is pretty unforgiving.
    I know a lot of people who tried to recharge some more freon, and then ended up bringing it in for a 1300$ new system. I'm not saying they didn't have bad compressors to start with, but it's relatively easy for someone who's not certified to screw things up...in a bad way.
    If you want to learn, then sure, grab some books, take a class, and have at it. I'm all for it.
    I only suggested the PC interface, because you didn't say what your problem was, other than that it never worked too good, which isn't very descriptive.

    Your best bet is to take it to a shop, the performance check/ basic diagnosis is only like 35USD or so. If it just doesn't blow cold, then you may could get away with a simple recharge, but I wouldn't assume that.

    as for the interface check out these threads:

    Mastero's Aircon

    My 'Beginning of an Automatic HVAC interface' worklog

    using the Fusion Brain

    It's not a very easy project, and mastero's Aircon is the most complete answer to date, but it as of yet is not an automatic HVAC option, but it works.

    My project is still under construction.
