Check your bulb, In the rear of the Generation 4 Ford Taurus, they use a single Dual filament bulb for the marker, turn signal, and brake functions. Chances are your bulb is burnt out and needs replacement.
turn signal relay is bad
your rear bulb is blown - replace the bulb The turn signal blinks fast because the bulb is going out. That is also why the others dont blink.
Buy a "highway" turn signal flasher
Check your bulbs and your flasher.
More then likely it needs to be replaced, if its the actual signal inside the car, turn it on check outside the car which one it is and replace!!
Why would you want the blinker faster. They should blink at factory specs.
its inside the hazard switch, usually tapping on the dash over the hazard switch will make it blink again
The flasher is broken. It is located inside the hazard switch and easy to replace. The switch is about $30 from the dealership and takes 10 minutes to replace.
Probably needs a fuse.
They don't really have a lead singer. Tom Delonge (the guitarist) and Mark Hoppus (the bassist) both do vocals pretty evenly, so neither of them is really lead.
