Check out the brake switch wire.if its having a cut in between or a loose connection in between this problem can occur.
There is a solenoid that locks the shifter in park until you press the brake.Try checking that solenoid and its associated circuitry.
also check the brake light switch,you might have a bad brake light switch. the brake light switch releases the shifter lock mechanism.

It's called the shift interlock feature. It's triggered by the brake switch so make sure the brake lights are coming on when this happens. If you have no brake lights, then you will have to test for power in and out of the brake light switch If the brake lights are working, then you'll have to get to the solenoid in the console or column. Disassemble as much as you have to to access the solenoid near the shifting mechanism. Us a 12v test light to test for power arriving at the solenoid when the brake is applied. If power is arriving and the solenoid is not triggering, the solenoid is bad.
Check for a good connection and try adjusting the brake light switch on top of the brake pedal. If that doesn't work, replace the switch.
Check the brake pedal switch and the wiring. You may have a broken wire.

Thanks. Keep updated for any more query. You can rate this solution and show your appreciation.

    Someone on one of the free forums said to turn the hazard lights on and then push that switch over one way or another. That fixed everything for now.

I have a 1989 ford f250 my hazard lights and brake lights don't work but my turn signal and tail lights do what could it be


Hi Jonathan,

I am not positive, but believe your Hazards work on the 'high' element of your tail lights, similar to how your brake lights do. Recall, when your lights are on, your brake lights are at normal illumination; when you press on the brakes, they're on their 'high' mode. If these high elements are burnt out, they won't illuminate; and accordingly neither may your hazards. Again, not certain on the hazards using the high element, but think so.

Good luck.

1995 Ford f250 brake lights don't work ad neither do the hazard flashers. I replaced the flasher node and the turn signals began to work but still no brake lights.


You may have a bad signal switch..Your brake lights run through the signal switch..Try hitting the brakes and move the switch around and see if your brake lights come on intermittently..

2002 Chevy Trailblazer Brake lights failure. All Three Breaklights will not illuminate when pedal is depressed. They will work when hazards are on, blinkers, etc. Main fuse under hood is good, bulbs work,...


Well, lets try this, if you have a trailer connector tapped into the tail lights check that for a grounded wire. If a wire has grounded or come free from the splices they won't work.

2004 Ford f-250 diesel. The hazard lights and turn indicator lights do not work. The fuse is good. The problem is not in the multifunction switch. I can not find a flasher relay.


Ford is notorius about the hazard switch going bad in the column. I have three trucks from 95 thru 02 that have the same problem. we just don't use the hazards and the turn signals work.
