Hi: I've done the search and it doesn't seem to have what I need. My 1994 Explorer with the factory trailer tow package has no brake lights. Tail lights and turn signals work fine. I've check the power to the switch with a multimeter, it is good. I've taken the brake light switch out and bench tested it for continuity by pressing it by hand. Took a lot of force but it does make a connection. Have not been able to find any unplugged plugs. Any suggestions? Hoping to avoid a costly trip to the *S*tealer. Thanks in advance for any help.
