I tried doing a search and found this thread, but didn't feel it exactly was on what I needed.

Anyhow, I recently connected the A/C high pressure line back up. I did a motor swap and broke the high pressure connector on the back of the compressor to the point that the plug wouldn't stay in, so the compressor wouldn't kick on because of that, or so I thought. I left it disconnected for a few weeks, but recently replaced the a/c belt and was able to get the plug to stay in the back of the compressor with tape and some other stuff (that's another story). And now the A/C runs and it's super cold. But I have frost build up on the drier and the lines going to it. The strange thing is the truck stays super cold, and it never gets warm. We were driving for about three hours with only stopping once, and the whole time the truck stayed cold inside, in fact one of our friends kept talking about how cold the truck is. But when I got it home, I popped the hood for something else unrelated, and noticed the frozen lines. After shutting off the truck, within seconds, it melted away. Today again we were out, but only made two short trips, and it frosted over again, but a/c never got warm. So first question, do I have moisture in the system, or is the drier needing replacing? I put a gauge on it, and running, the pressure is around 45psi after i took a short trip around the neighborhood. And the second question is, would this last until next month? I have A/C manifold gauges, vacuum pump, and a recovery unit I have saved to buy. I plan to buy them so I can have it on hand for myself and family, but planned to discharge, weigh, and vacuum down the system. Thanks again.
