2013 corrolla brake light on driver side keeps blowi g

Hello, Near the tail light housing you will find a ground wire connected to the chassis. The first thing to do is make sure that ground is clean and tight. Next, check the wire harness leading to that light bulb to ensure it is not frayed, burnt, or cracking. Next, ensure that water is not making it into the light socket. You can do this by spraying the light from the outside of the vehicle with water to see if you can get the light to blow.
