I'm still having problems with my A/C. I washed it this weekend and the A/C wouldn't work for about 20 minutes.

The following items have been replaced:
serpentine belt
tensioner pulley/lever
a/c speed relay $$$

Is there something around the windshield area that I can check? This is the only area I can see thats get wet when you wash the car. The splash shield under the car is in place.

Any help is appreciated.
