Transmission shifts fine underneath. Currently the trans selector on the column seems to be locked up. Anybody had a simular issue? Thank you, Dikthod

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..."

Verify your brake lights are working. If they're not, you can shift it into neutral BEFORE you start the engine, then put it in gear. If this is the issue, most likely you haven't had the cruise control recall done and the fuse popped.

Also, there are two torx head bolts underneath the column that come loose. Pop your head under the dash and wiggle the shifter. If they're loose, you'll see them.

First, Thank you to the replies above, this gave me a great quick start in the right direction. I was about to tear apart my steering column...lol!!

Issue: Will not shift. Fuse #13 repeatedly pops

Would anyone have further info regarding this issue? I have tested the brake light switch and all seems well. as soon as I turn ignition and press the brake pedal Fuse #13 pops. I removed all Stop Lamps and reviewed both Ford and Haynes Wiring diagrams and have not come up with anything except about 12 blown fuses. I tested wiring and all seemed fine, No short to ground on "Light Green" or "Light Green/Red Stripe Wires". Is it possible for the Multi-Function switch to be causing this issue.

Chances are you haven't had the recall done yet.

Unplug the wire that on the end of the master cylinder. See if the fuse still pops.

Good tip, Thank you.

It looks like I do have the recall, going to research that. I disconnected and tested with same results. I attached a Trackback thread that I found and I'm leaning towards that being my issue

Thanks everyone for the info and replies! Between this thread and a few other resources, I was able to locate my issue.

My issue is the connector for the Upper Brake Lamp behind the Driver's Seat is just a mess. It is completely corroded so I will be bypassing that connector. Worked this issue for about a week and I ruled out the Upper Brake Light due to the fact that my Hazard switch did not blow the fuse and everything worked. Once I realized that the Upper Brake Lamp is not connected to the Hazard Circuit :doh0715: , I quickly located my problem, using all the resources I mentioned above.

Thanks again all!
