The brake light switch is bad. It's under the dash, and is switched by the movement of the brake pedal.
I have a 1996 Grand Marquis. If one of the brake lights goes out the signal on that side flashes faster. I would check the brake/tail lamps.
Brake light switch stuck, defective, or out of adjustment.Brake light switch stuck, defective, or out of adjustment.
A short in the brake light circuit.
The computer has detected a problem and there is a code available for you to read. That is the purpose of the light.
LOL! I would ask the question why the heck would you need an alarm on a 1984 Lincoln grand marquis?? :O
there is a awitch on the chassis rail that needs to be bled, or replaced either go to a mechanic or get a workshop manuel this switch is called hydraulic control unit (HCU)
There wouldn't be.
Into Park or out of Park?
first check your brake fluid it may be low then check the switch at the emergency brake lever it may be stuck
