Q: There are minor electrical issues that fix themselves after turning the car off.

There have been minor electrical issues with my car lately, usually after rain. The first time was 1 week ago when I rolled my window down, and instead of it automatically stopping a little over halfway down, it went all the way down. When I tried to roll it back up, it wouldn't roll up. So I turned the car off, waited 5 minutes while I looked up stuff pertaining to a non-rolling window, and when I turned the car back on the window rolled up and down again just fine. Then, today (10/29) I was leaving work and as I turned on my right blinker, it was blinking at double the speed (at least), so I pulled over and checked both blinkers. The back was not blinking and the front was blinking extremely fast. So I turned it off and got ready to change the bulb in the back before deciding to just head home first, and when I turned my car back on again after a few minutes the blinker was working just fine. Are these issues with the blinker/window themselves, or the electrical system as a whole?
