Lincoln/Mercury Repair: Brake Lights stay on, torque converter, brake switch


Question
Why would brake lights remain on when car is unocupied? kills the battery  

Answer
Hi Raul,

You have a bad brake switch. Not only does it kill the battery but it will also prevent your torque converter from going into lock-up mode and will fry your transmission. The brake switch is located up high on the brake pedal. If you had supplied me with the year and model, I would have happily giving you the part number. Easy enough to purchase this switch and it shouldn't be expensive. Less than $50. Takes about 10 minutes to install.
