Brake lights stay on

This issue is most likely the brake light switch has shorted and keeps the brake lights on.

Here is a guide that will talk about how this switch works:

I would suggest starting with adjusting the switch as it may just need to be backed off a touch. However, if this doesn't work then you will need to replace it.

I attached the process for both of these below. Please let us know if you have questions. Thanks
