my car's hazard seems to have a problem.. sometimes when i start the engine, it already starts to light up and it never stops.. so i turn off the engine and it still goes on for a while then stop.. after a few minutes.. i start the car again, the hazard lights up again.. the only way to make it stop is to remove the car;s batt. i went to different mechanics and that;s what they did.

what;s wrong w/ my car.. and how can i remove the batt by myself.. i'm pretty scared to do it
