Avalanche Z-71 V8

I bought the Avalanche during the recent drought. A/C worked fine until the rain came. Now the A/C compressor clutch disengages intermittently when it’s raining or the humidity is high. When the compressor is running the A/C cools very well. On a recent trip while the weather was very wet and the A/C would cool for about 15-20 minutes, then blow uncooled air for about 20-30 minutes, then cool for a while, then not cool for a while.
