Already replaced brake light switch, multifunction switch, hazzard turn signal switch. The bulbs look fine. Fuses look fine. Flashers don’t work either, turn signals when operated separely do. Rear lights only on when headlights are on, but do not brighten when pedal is depressed. PLEASE HELP!!!
Changed all the bulbs, to no avail. Where do we start next?

And How do I change it, can I just use the normal bulbs for turn signals? Or do I have to buy something different, I normally have no problem finding the son of a gun on any of my other cars, but I cannot find it on the taurus, thanks alot!!
And for the smartA** that answered earlier, I know it is in the trunk, but I can’t seem to find it, I pulled what I thought was the bulb out and it was just wires.
