Default Security light on when it rains...

This happens sometimes depending on how I wash it but I figure something's exposed that shouldn't be and is shorting a bit when it rains or I wash my car. currently its parked on a hill facing down so that adds another bit of problem.

anyone go through this and did it become something worse?

If it dries up it's fine, ie after a day or a long drive.

I had those symtoms, turns out the grommet in the firewall under the PCM wasn't seated, it would let water get on the BCM and until it dried out again I had trouble starting the car (security light would come on).
