This has been annoying me for about a year. When I start my car the blinkers flash,the dash lights flash and the driver door ajar light flashes. It all started when I left my lights on and had to get a jump. My friend jumped me with his mid 90's cherokee and I don't know if it is from him revving his engine and surging something or what. If I turn my headlights on the lights don't flash on the outside and I just get the annoying blinker sound. It stops flashing about 5 mins after the car has started and all lights stay off after that. It is getting annoying because recently I have killed my car twice because I forget to turn the headlights off when it is still light outside. Any help would be greatly appreciated.
