After bleeding the brakes (see related post from today), I happened to notice that the brake lights don't come on even though the pedal has a nice firm feel and there are no apparent leaks. All tail lights, turn signals, and license plate lights work, so I am thinking it is isolated to the brak lights and not an issue with the whole rear part of the harness. When I looked down at the brake switch, the connections were kind of loose and there was a tiny spring that looks like it had dislodged from the switch. I am sure the switch is part of the problem and I plan to replace it, but I am also worried about the wiring as well.
After doing some searching of my own on the topic, I read some other posts where people had touched the two wires together and the brake lights come on. When I did that last night, my brake lights did not come on. As luck would have it, my circuit tester broke in my hand, so I haven't been able to test for electricity all the way to the switch. However, if I touch the two wires together and no brake lights come on, doesn't that give me some indication that there is not electricity getting to the switch and there could be a problem elsewhere in the harness?
The idea that there is something wrong elsewhere in the harness is what worries me, since I don't have much experience with the harness and dealing with electrical issues in general.
Given my lack of experience, I guess I am asking if you more experienced people can help guide me in terms of what to look for next, so I can try to trace back to the root cause of the brake lights not working.
