I had the same problem. Turned out to be the switch itself.

Where did you buy switch, it looks like they are a little hard to find?

The seat controls on the sides of the seats are notorious for constantly running once they get wet. These modules can take weeks to actually dry out, and the constant running can kill your battery. This sounds exactly like the problem you are experiencing.

Corvette Recyclers is one place that you can locate these modules. There are other Corvette salvage yards on the web but that is the first one that comes to mind.

The car hasn't been in the rain for years, but all its been doing in No. Illinois is raining----must be high humidity

Sorry. I did mean the switch in the seat. Unfortunately I'm not help on sources, mine was a warranty replacement. But good luck.

Although the car may have not been in the rain, you have washed it. It only takes a couple of drops on that module to create havoc. That's how I found out about this problem.
