Try to put it into neutral the hit the button. The system is electronic and has a memory. If it is not used frequently it will forget what to do. To re-program it, disconnect the battery for 30 minutes. It will need to be used once a month or so to keep it's memory after it has been re-programmed. Try to do this on dirt or wet pavement to prevent possible damage. These uses can be short in duration.

97 Ford Escort is not shifting?

Are tail lights and brake lights the same on a 1999 Nissan altima?

Tail lights and break lights are different things pretty much all the time. You see, tail lights run all the time the car is on and break lights only turn on when the break is pressed. If you would like to find out which lights are the breaklights, have a friend watch the back of the car, turn it on, push the breaks a few times and see which lights flash. The lights that flash are your break lights!

You may have a bulb that that brunt a element which than crossed the other element cause all lights to come on a one time. I have seen this before. If this does not light all bulbs when the brakes are applied, then I would be looking in the front lights, if it does I would look in the back lights.
