Have a new to me 2003 Honda Accord LX with 80,000 one previous owner miles. At first the car was just the normal kind of old man dirty and beat up. I replaced a few things here and there like bulbs that were out and a knock sensor that was disconnected. All seemed well until while driving down the road, my trunk popped open on its own. The sum of the electrical gremlins is as follows:

Trunk while pop open when brake pedal is pressed (trunk pop is currently disconnected now)
turn signals willl not work when post is engaged, but they do spazz out on their own
door locks will spazz out and key fob has no impact on door locks whatsoever
fuses are all good
hazards work fine

The battery is now new, and I am at a total loss. Before I bring it to a mechanic and have them try to get to the bottom of this, I figured I would ask other Accord owners if they have ever come across anything like this. Thank to anyone that has any input at all!
