A small leak is bigger in higher atmospheric pressure.

Put A/C hoses on it after steam came out the center vents. The gauges read weird pressures. The previous time was a small charge. A small PSS was heard while removing the caps. Both cores were tighten. Each valve core turn just enough to know it moved. A quick 30 min vacuum was pulled. Due to high humidity, it didn't pull as low as I would like to see it. The vacuum pulled the first can great. The remaining R134 was pulled when the compressor kicked on. Before reaching engine operating temperature and second can, the condenser fan kicked on. The auxiliary fan had not been kicking on with the A/C command button. Hopefully, now the fan will kick on to cool faster than having to drive off right away.
