TAKE IT TO A REPAIR SHOP SO THEY CAN LOOK AT IT! SOUNDS LIKE THE BRAKE LIGHT SWITCH. BUT IT WILL HAVE TO BE SEEN TO TELL.

I'm gonna guess that it's the brake lights on. Here's what you need to do. Go under the dash and find the brake light switch. It should be up high and in line with the brake pedal. Where the plunger from the switch strikes the brake pedal there is supposed to be a little mylon or plastic plug. This plug can fall out after some years and it leaves a hole that the plunger can go through and thus the switch doesn't get pushed in. What I do with these is find a small bolt and nut and put it in that hole where the bolt head will contact the plunger. You will likely have to adjust the switch after this.

Thank you for answered, I will look the break light as you said, but i wondered that, i did not turn the key on why the break light can be on?

Because in most vehicles the brake light circuit has 'unswitched' (constant) power. Also I can appreciate importmans solution (I admire those that can improvise and or actually repair as opposed to simply replacing), however , A brake light switch normally is not an expensive item and may save you from an expensive rear ender.Call dealer and NAPA auto parts if available in your area and compare price. BUT test first , repair/replace second.

Ziptie is correct in that the brake lamp circuit is basically "live" 24/7. However he may have slightly misunderstood my repair. (Possibly I didn't explain it well enough). In the scenario that I described the brake light switch itself is not faulty, therefore replacing it will serve no useful purpose. Rather, the part I'm suspecting to be at fault is what I would refer to as the "striker". This is what causes the plunger on the switch to go in and open (open meaning NO current flow), the circuit when the brake pedal is released. Without the nylon insert the plunger just goes through the hole in the "striker" and the switch remains closed (closed meaning the current DOES flow through the circuit to the brake lamps). I fully agree with ziptie that you should check before repairing anything. In this case all it takes is one look and you can see if the nylon insert is missing from the upper part of the brake pedal assy. If so, this is a simple (almost free) repair. And I have seen it many times. Good luck.
