Just trying to see if anyone ever experienced this. I have a 2000 civic sedan shell I was moving in my garage. I put a battery in it to roll the windows down, and all the electrical functions are reversed. Horn blew without pressing, up is down and down is up on windows, lock is unlock unlock is lock on doors, on is off and off is on for hvac blower motor. Disconnected battery quickly and haven't really messed with it since. Just wasted to see if this had ever been encountered. AGAIN THIS IS A SHELL ONLY, AND WAS FINE BEFORE PARKING.
