Just noticed my cruise control does not work when my headlights are on. Also my rear right break light works only when no headlights are on, the left one and centre window not working. When the headlights are on, no break lights work. Surely this is wiring or relay? Please help. 2002 au model

replace all globes - check earths at rear lights - especially right one(it is picking earth up thru tail light circuit which it looses when lights are turned on) -no brake lights = no cruise control-

Ok. Thanks for the advice.
