Water is an electrical device's worst nightmare.
Well, that and rogue power spikes
David, I'd park the car for a good two or three days in a covered environment if it starts raining again. Let the car dry out, sounds like you had a short in your system due to waterleak in the interior. Check your rear hatch seals and side door seals. Has your car ever been in an accident? Could the door frames be warped/bent? I've had a problem with my driver-side window creeping down on me a bit (damn old hand-crank windows), never to the point where it's wide open, but it's not a perfect seal and water sometimes gets in, especially when I'm washing the car with a pressure washer.
Jay, good question - dunno - could have blown the relay if enough water got into the signal housing. Isn't the relay like a $10 item? Just try swapping it ...
I took my car for a swim at the drive-thru for McD's on StillCreek yesterday. Ran a little rough after, actually thought for a second I may have skipped a tooth :crazy: ... but she cleared up after a bit.
Anyways, back to work.
