A/c Woes

[E150GT]

This weekend it rained like a mother and i got caught in it in my 86 420sel. Water got the engine all wet and I had turned off the a/c which was blowing cold. I noticed my aux fan was blowing with the a/c off and my temps were only at 80c. I shut the car off and came back about four hours later and the aux fan turns on with the ignition and the a/c off. Now the compressor won't kick on. I drove it about 20 miles highway and still didn't turn on. As i pulled into my parking spot I turned it on and the compressor worked, so I turned it off and went to bed. This morning when I turned the car on the aux fan kicked on right away but the compressor would not. Anyone have any ideas why my compressor wont work after it got wet?
