I have parking lights but when I push the break pedal, the break lights don't come on. The odd part is that the middle break/parking light (on the top of the read window) works fine. I checked the fuse and the bulbs and they are fine. Any suggestions?

Turn signals work? The brake lights are the same as the turn signals. Sounds like the turn signal switch is th eculprit

Get your test light out. At the turn sig switch connector- test white wire for power when brakes applied. If none there is a break in the wire from brake switch on pedal, if it has power, test the Dark green wire for power and the yellow. If none the turn switch is bad, if they have power there is a break in the wiring or possible bad plug in the body harness between switch and the rear lights

I went out this morning to go to work and the turn sig flasher had stopped working. After work I stopped at an auto store and picked up a new one and (of course) they gave me the wrong flasher. I got the 4 way flasher instead. Are the break lights and the turn sigs on a circuit and the problem? I'll be replacing the flasher tomorrow. It seems odd that after you asked me about the turn sigs that the flasher died on me. Right now, it's 17 degrees here so the less i'm outside the better. Lol
