I just bought a used 2002 Focus ZTS. After a couple of days, someone stopped me and said my brake lights are not working. After checking it out, my center brake light is working. It is the 2 on the sides that are not. I began reading online forums for help, I still have a couple of questions.
Some people say it could be the GEM. Where is it located? Can i test it to see if it is the problem?
I've heard you can unplug the brake switch and the brake light stay on. Is this true and where is that located?
Or am I barking up the wrong tree entirerly?
Any help would be appreciated.
