The right directional signal on my girlfriend's car doesn't work. When you
turn on the right directional signal, both the front and back directional
light turn on but don't blink. They just turn on and stay on. The flashers
work ok. The left directional signal works ok. Any ideas on how to fix it?

I thought it might be the capacitor but the 4-ways work ok and the left
signal works ok. Could it be a fuse? The switch? What would cause this
behavior?
