Hazard lights come on by them self while the car is parked

You have constant power to the hazard switch. Replace the switch. it is shorting out.

Disconnect the Battery and Charge it as a STAND ALONE CHARGE (not connected to the car), You may have a bad ECU.

The parking lights should be on a different circuit from turn signals - hazard lights. The bulbs usually have two filaments, one for each circuit.
On most models there is a tail light fuse and relay that handles front and rear parking lights.

YOU MIGHT HAVE A BURNT OUT RELAY IN FUSE COMPART UNDER YOU CARS HOOD CHECK THAT OUT THRU YOUR CARS MANUAL,IT WILL SHOW YOU WHICH RELAY IT IS?

sounds like the hazard switch is bad. take it off and try another.

The flasher for both is located in the hazard switch it self, pull trim off around switch unplug and replace, part will be a dealer item only part place will not have this part.

sounds like the body control module has gone bad. have the vehicle scanned - a multiple amount of BCM codes will confirm this. only other suspicion would be if there is an aftermarket alarm / remote starter could cause these symptoms.

Start by checking the fuses. The parking & headlamps work off the same switch. The back-up lamps are on a different switch,which is activated at the transmission.

one of your bulb is blown one bulb will shut the rest off check all your bulbs.

you can look to the left of your stearing wheel and there is an "ashtray"/ cubby hole you pull that down and out. There lies your fuses. On the ashtray itself on the side of it tells you what each one is and what amp it is. Thery are picture coded but pretty self explanitory. Hope this helps you out. Have a good one!
