yo,
Check all brake light bulbs; regular 1/4 panel mounted and high mounted;
Brake Shift Interlock; "These (and many other) vehicles are equipped with a Brake/Shifter interlock for safety. This system requires the driver to hold the brake depressed before the shift lever can be moved from the Park position. There is an actuator (solenoid) on the left side of the steering column under the dash that disengages the shifter lock when the brake is depressed. In the event this system malfunctions, the shift lever may be stuck in the Park position. One cause of this complaint may be due to a faulty brake switch circuit. If you experience this complaint always check for blown fuses and brake light switch operation before proceeding with other work."

Brake Shift Interlock, Inadvertent Disablement TSB 99-13-9 for 94-96; "...Corporate, municipal, or police fleets may have had their 1992-1999 Ford Motor Company vehicle modified to flash the brake lamps whenever the police lights or other aftermarket lights are turned on, which may disable the brake shift interlock. The brake shift interlock is a feature that prevents the vehicle from being shifted from Park unless the brake pedal is depressed. Disabling of the brake shift interlock feature may enable the operator to inadvertently apply the accelerator instead of the brake pedal and simultaneously shift from Park to a Drive gear. ACTION: As appropriate, dealers should advise owners (including corporate, municipal, and police agencies) that any vehicle that has been modified with a connection to the brake circuit, or that electrically interfaces with the brake lamps in any manner, should be disconnected IMMEDIATELY and the emergency lighting system should be modified in a manner that does not interfere with normal vehicle operation or the brake shift interlock. In addition, if the high-mount stoplamp flashes when the police lights are on, the modification does not conform with Federal Motor Vehicle Safety Standard (FMVSS) 108 which requires that the high-mount stoplamp only illuminate when applying the brakes. Installation of warning lights should only be performed with a completely separate electrical system, without connection to any existing vehicle wiring. Connection of aftermarket electrical equipment into the brake lamp circuit or any other circuit which is connected to the Powertrain Control Module (PCM), anti-lock brake computer, air bag system, or any other vehicle system, will cause vehicle malfunction..."
