I purchased a 2003 toyota tacoma. i have had a problem with the brake light coming on in the winter. when i press the brake the first time the light stays on until the truck warms up; then goes out. i took the truck to toyota and they couldn't find a problem. now the light is periodically coming up and staying on a couple of minutes in the warm weather. i again took it to toyota and they again couldn't find a problem. *jb
