My cadillac cts 04 the break lights wont turn off. i already changed the break light switch im thinking its the fuse. wats the name of this fuse and were do i find it? any help is good thank you

Hello. Under your brake pedal is a switch with a plunger on, that activates your lights when depressed. Just follow up along the pedal and you will see (probably) a white switch. It sounds like the plunger switch is stuck in. These are quite cheap to replace and you might be able to prise the plunger switch out to turn the brake lights off. If it was a fuse it would not work. Can you leave feedback if this helps. Thanks
