Nissan Altima Brake And Tail Lights Q. I have a 1995 Nissan Altima. Recently I had some work done on the vehicle and the fuel pump was replaced. Since then, my brake lights come on when I turn on the headlights. Also, the cruise control will not work if the lights are on. Is it possible that they crossed a wire when they were working on the fuel pump? THANKS!!
Watkinsville, GA A. If all they did was replace the fuel pump, I don't see how they could have crossed any wires. You don't need to remove the fuel tank to replace the fuel pump and there is only one connector to the fuel pump and it will not fit into anything else. Every time I see a problem such as you describe, it is almost always due a bad or incorrect tail light bulb. The tail lights take a dual filament bulb. As you can see in the wiring diagram, if you put a single filament bulb in the tail light socket, it will bridge the two contacts and turn on the brake lights. The reverse is also true. If you step on the brakes it will turn on the parking light bulbs. Something you would not easily notice. The reason the cruise control doesn't work with the brake lights on is power is on both sides of the brake light switch and the cruise control thinks you are stepping on the brake and will deactivate the cruise control. So the first thing to do is to check and replace any bad or incorrect light bulbs and check the wiring for any short or crossed circuits..
Probably a brake light switch.
1 of 3 reasons why, your head lights are on, your reflector lights are on ,or your brake sensor is broken
Brake lights could stay on in a 1999 Dodge Stratus because of a short in the wiring. If the headlamps are off and the brake lights are still on, check the wiring for the brake lights that is inside the trunk. Sometimes cargo in the trunk can interfere with the lights.
If the brake lights stay on that probably means the switch on the brake pedal that activates them is defective.
Adjust the brake switch which is above the brake pedal.
check the brake light switch
The brake relay switch is bad.
Bad brake switch
the brake lights are on a separate cuircut,if your brake lights are staying then it will be a fault with the brake light switch. the switch is located under dash,and will be on or very close to brake pedal.
Brake light switch out of adjustment or defective
It is probably the brake lights that are on due to a misinstalled or damaged brake light switch.
If the brake lights stay on when the car is not running on most vehicles, including the 1994 Dodge Intrepid, there is probably a short somewhere in the wiring to the brake lights. The first place to investigate this problem would be the wires along the firewall that control the brake lights. Also, check the brake light switch above the brake pedal.
The brake lights on a 96 Jimmy are operated by the brake light switch, mounted on the brake pedal assembly. If the switch is bad the lights could stay on or off, or be sporadic.
are you sure it is the brake lights and not the tail lights. if it is the brake lights you most likely have a short some where. go to a auto eletrican It is the brake lights which turn on. Short in the switch or the wiring?
Possibly a defective brake light swith stuck closed.
Brake light on 1994 Honda civic staying on.
yes, they do
check the brake pedal, there is a switch on the back of the pedal that depressed when the brake is depressed that turns the lights on, when this is loose it keeps the lights on.
It sounds like you have a faulty micro switch on the brake pedal.
probably a faulty or mis-aligned brake light switch.
Check the brake light switch ,on the brake pedal. Might need adjusting.
This is usually cause by a stuck brake light switch on the brake pedal. Replace it.
Under the brake pedal is a brake light switch that when you press the pedal it hits it and makes your lights come on..sometimes when they get weak the pedal depresses them simply from the weight of the pedal and they stay on..Have a friend get inside the truck and pull UP on the brake pedal as you look at the lights..if the brake lights go off when they pull up on it..then it is that switch under the brake pedal
There could be several possible reasons why the brake lights stay on all the time on a 307. The most common reasons would be a bad relay or a bad switch.
