Came down to the garage this morning, and our '98 Civic EX's dome light was flickering, and the power locks were clicking up and down randomly.

The car has been parked in the garage for about a day, with the doors unlocked.

I opened the door, and started the car normally, shut it off, and got in my car to go to work. It seemed to have stopped doing it after that, but I have no idea if it was flipping out all night or what.

Anyone know what might have caused this?

Thanks

 

could be moisture in the relays.
do you have an alarm system on the car..?

 

you most likely had this b!tch clogged in your wire harness..

 

No alarm - the car is completely stock - radio, everything.
I talked to my wife, and she remembers the car doing this once before.
