2006 Holden Barina TK. Hazard lights come on randomly and won't turn off, even if you operate the hazard light switch.

it will be a micro switch either in the lock mechanism or activated by one or the boot hinges.

If all else fails, test with a test light or a multimeter set to VDC.

I have a 2006 Holden Barina & indicator stalk won`t self cancel

I got a new battery for key , I think to avoid it being complicated you drain out the fluid , bleed the stuff left after a month by your master cylinder and look where the hose enters the car and booster and check it by clamping one end to the intake , iT gives air back to the vac or if you locate the fan fuse 20 renew it it blew also the fuel so release pressure change it if it don't solve is ? Have you got any code

hazard light switch normally has the flasher relay in it if the back of it is size of a matchbox,would replace that first

these had issues of not starting when cold and missfiring only when cold
this was due to valves sticking due to carbon build up
head of and get valve guides modified as per holden info (scrapper counter sunk guides)

battery and dirty terminals is a good assumption
have the battery load tested

It is in Theft lock from the loss of power. Contact your local dealer for help getting it unlocked.

your holden is a daewoo get rid of it

check the turn signal relay that usually goes before the fuse
