I have a 90 4runner and my brake lights do not work at all. The brake light switch was changed and new bulbs put in and it worked for 2 days and then stopped again. I'm not sure what else to check for, if there's a break in the wire along the way somewhere or what. How hard would it be to run new lines the the taillights? Any help would be greatly appreciated thanx.

 

have you checked the fuse??
