So I have noticed now that it is winter. Sometimes my radio acts weird, presets jump around or radio is turned on when I had it off when I killed the ignition, but it clears up after a week or so.
Recently my A/C will be on when I had it off before starting the car. No big deal I just hit off.

The only thing I noticed that is triggering this, is these strange things always happen after it rains. I live in LA so rain is few and far between but I cant help but think something electronic is getting wet.

Any one have an idea where I should check to make sure things stay dry or are not getting wet? Dont know much about electronics on thi car but I just want to make sure its not a rubber seal or some housing that is loose and getting wet making these strange issues occur.
