hi i have a 90 integra, the brake light wont turn off even when the car is not turned on. is the problem with the brake light switch or fuse? anyone know what it is. also where is the bake light switch located in the car im not sure. thanx

 

Have you checked the brake fluid level? I would do the easiest/cheapest things first. The fuse would be next on the list for me and them the switch. All of them aren't rediculously expesive or hard so you could just do them all....
I think the brake light switch is way up under the dash at the top of the brake lever assembly. Lay on your back in the drivers floor and look around with a flash light.

 

Make sure the E brake switch is functional, check fluid level then look at the switch under the dash.
