The doors would open and close spontaneously; the car would vibrate erraticly when i used my high beams; alarm would go off randomly; left turn signal would blink REALLY fast (like ones found on rice rockets; fast turn signal = 50HP). All this...because of a dead battery. So dead, it wouldn't even charge when boosting/jumping. You might want to check the battery first. Right now, i STILL dont have a battery. Gotta settle for a 83 Dodge Ram Van heh heh.
