So I own a 07 civic si , and my defroster always stays on . I can't turn it off .

Obviously it's off when the engine is off but everything else is off , the ac , the velocity of the air is off . Idk how to turn it off .

Does anyone one know how to ?

 

Is the defroster actually on or is the bulb/light on? There's a difference.

 

Both bro , the light is on . ( yellow ) can't turn it off

 

So, bro, I'm guessing you haven't done anything besides looking at it be on. Maybe try getting into the dash and examine the switch?

 

No it's not the fuse . Basically it's on all the time the car is on & its letting out air thus making waste more gas . It's even blowing air out when the air velocity button is on " off "

 

Who said anything about the fuse? It is like that the ONLY way your going to find out is if you pull apart the dash and run some tests on the switch itself. Why is that such a hard concept? It's not going to fix itself by you looking at it.
