So im new to the site and not exactly sure if im doing this right, but here goes. i recently got an 89 toyota supra. on the dash my break light is constantly on (which im pretty sure is just a bad sensor for the e brake), and my radiator light seems to go on and off randomly. any ideas as to what might be causing this? another bad sensor or something more serious? i dont know a lot about cars so any ideas would be helpful. thanks.
