    I went for a drive today in my 99 Tahoe and turned on the A/C fo the first time this spring and there was nothin. It seemed to work fine when I bought her in November but hadn't had it on since. Do I have to buy a couple of cans of that A/C recharge or what?

    You should only need one can, just get one with the pressure gauge built into it, they are anywhere from $15-$20 at oreillys, my suburban didnt even take a full can last summer when I did it so one should be fine, check around the compressor and all the lines for any leaks too.

    'There was nothing' meaning.... no cold air? Or no air at all? Is the compressor engaging?

    Sounds like a system leak. Always turn on the A/C for a couple minutes every couple weeks to lubricate the system, especially the seals. The older the vehicle, the more important that is.
