Question A/C Intermittant Cooling '93 300E 2.8

As predictable as the sun raises everyday, my a/c will not cool after I go through a car wash. Sounds silly, but it's true. It will blow warm moist air.

And it will take hours before it engages again. Even shutting down the engine and waiting doesn't solve this one.

I decided to check all the plugs and connectors leading to the compressor and the freon container ( not sure what you call it - the one with the sight glass) and wiped down the connectors and prongs. They were all moist and dirty. Since then, the a/c is cooling better than before. But I have not yet driven it through a car wash to test it out.

Any ideas on what may be the cause? Did I pinpoint it by cleaning the connectors?
